Did you know that every year, the week of October 10 is National Metric Week? There are many great reasons to recognize and celebrate the metric system, the first being its ease of use. Because of this, it’s essentially accepted as the standard measurement system worldwide (with very few countries holding out on full implementation), allowing for consistency in measurement on an unprecedented scale. Subsequently, the metric system has been instrumental in facilitating global trade and other collaborations across nations! The world as we know it would be very different today were it not for the metric system.
The week of October 10 (10/10) is a fitting window of time for National Metric Week, considering that every time you count 10 of a given base metric unit, you’ll get 1 of the next unit.
The units of distance in the metric system are:
millimeter = mm (1/1000 of a meter)
centimeter = cm (1/100 of a meter)
decimeter = dm (1/10 of a meter)
meter = m (1)
dekameter = dam (10 meters)
hectometer = hm (100 meters)
kilometer = km (1,000 meters)
Ten of any of these units is equal to one of the next unit up:
10 millimeters = 1 centimeter
10 centimeters = 1 decimeter
10 decimeters = 1 meter
… and so on!
Calculating area or volume? No problem! You can convert square and cubic units similarly. Square units measure area, calculated by multiplying length × width in many cases. Both the length and width of a given area each change by a factor of 10 (10 × 10 = 100) as you move from one unit to the next:
100 mm2 = 1 cm2
100 cm2 = 1 dm2
100 dm2 = 1 m2
… and so on!
This means you move the decimal point two places (100) left or right for each unit down or up from your starting point:
Convert 276 km2 to m2.
When we go from a bigger unit to a smaller unit, we move the decimal point to the right. Because “square kilometers” is three units up from (and a bigger unit than) “square meters,” we move the decimal point six places (3 × 2) to the right:
276 km2 = 276,000,000 m2
In that vein, when we use cubic units to measure volume, we’re looking at length × width × height in many cases. Length, width, and height of a given volume each change by a factor of 10 (10 × 10 × 10 = 1,000) as you move from one unit to the next:
1,000 mm3 = 1 cm3
1,000 cm3 = 1 dm3
1,000 dm3 = 1 m3
… and so on!
This means you move the decimal point three places (1,000) left or right for each unit down or up from your starting point:
Convert 785 cm3 to km3.
When we go from a smaller unit to a bigger unit, we move the decimal point to the left. Because “cubic centimeters” is five units down from (and a smaller unit than) “cubic kilometers,” we move the decimal point 15 places (5 × 3) to the left:
785 cm2 = 0.000000000000785 km2
As the metric system is a decimal (base 10, “deci” meaning “10”) system, in many cases, you don’t need to calculate to convert … simply move the decimal point left or right! This is why it’s extremely easy to convert between metric units—much easier than with other measurement systems out there!
The metric system is also known as Le Systemè International d’Unités—SI for short!
The original “meter” was defined as one-tenmillionth of the distance from the equator to the North Pole, measured along the prime meridian. Today, it is defined as 1/299,792,458 of the distance light travels in a vacuum in a second.
Generally speaking, metric prefixes that indicate units larger than the base (i.e. kilo-, tera-, giga-, deka-) have Greek roots, while prefixes that indicate units smaller than the base unit (centi-, deci-, milli-) come from Latin. (There are exceptions and overlaps, of course.)
The metric system was officially introduced in France in the 1790s. Over the centuries, most countries worldwide adopted it as the standard measurement system. While most countries use metric units exclusively, others have yet to adopt it fully.
With many elements of daily life measured in miles, inches, feet, pounds, ounces, quarts, gallons, etc., the U.S. remains the only industrialized nation that has yet to go fully metric. However, it is the established measurement system for certain industries, particularly within STEM fields. Other metric holdouts include Myanmar and Liberia.
Metrication is the process by which countries go metric!

Did you celebrate National Metric Week? If so, how?
My son started with Mathnasium in the fourth grade and has gone for four years. He is currently taking tenth grade math in his eighth grade. Two of the last three years my son's math was distance learning with a computer and he didn't have the resources of a full time math teacher. Mathnasium gave my son the ability to interact with an instructor and get his questions answered. They worked well with my son and he enjoyed learning at Mathnasium. The tutors are very knowledgeable and friendly.
Mathnasium has offered great support for my daughter. She didn't want tutoring at first but once she tried it she loved it. The tutors have typically been able to help her grasp new concepts in one sitting so she can move on and master the skill. The staff has always been great to work with!
Emily did a great job tutoring Colin and preparing him for his pre-calc final. We want her to know he got a 93!!! We would absolutely recommend her, and we are so grateful she worked with him. She did a wonderful job holding him accountable and helping set expectations about what to expect the remainder of his junior year.
Our kids have been attending Cary Mathnasium for 2 years now, and we're very happy with the results. Before Mathnasium, one child's math final exam grade was almost an F. With Mathnasium, this year's final exam grade was a 98%. We believe there's no way that would've happened without Mathnasium! Thanks guys!
It really help my child get through her class! I have already told some parents of students to try it if their child needs extra help. I only wished that I would have gotten a email receipt every time I Schedule a class with the time and date. I had put down the wrong time a couple of times in my calendar because of trying to schedule to many at one time and mixed up the times. The receipt would have help me remember to how many privates I used. So I could reorder more.
All of the teachers are caring and met my son where he was academically. Love that they assess and then come up with a plan that we can chart and monitor. Have also been great about helping my son prep for a standardized test.
Thanks to Mathnasium of Cary on James Jackson Ave, my daughter's skill set has changed dramatically over the last several months. Her confidence in Math has increased 10x, she is now engaged in the classroom & her test results have improved. She is excited to go every week and loves the staff there. Not only are they experts in this line of work but their approach, patience and never-ending encouragement has made my daughter blossom in an area where she felt like a failure. I'm so excited to see her now being successful and would encourage anyone who is struggling with Math to make the investment...it's totally worth it!
We were looking for a one time refresher for CCM1 and had a great experiences with qualified instructors and ease of registration and assessment for the appropriate month's worth of work assigned to our son. thank you!
Thank you for making math fun - my son looked forward to his sessions and never complained about having to go. When he finished his last session, he actually said he wouldn't be disappointed if he could keep going once school started!
Mathanasium has been fantastic for my first grader. He enjoys math and wanted a challenge. The Mathanasium group is able to challenge him with an organized approach that fills in some gaps that he missed due to moving ahead quickly. He loves the teachers and actually wants to... and looks forward to his time at Mathanasium! In fact, he wants to go more than once a week. Somehow, the teachers are able to challenge him and keep him loving math and coming back for more. As a parent, I appreciated the pre-testing which highlighted gaps and strengths. It's been a wonderful experience for us.
We have always had success with your teachers. We wish there was a program in place to continue with sessions when our son is not in math class at school, but wants to keep his math knowledge fresh in his mind.
Regarding the closure due to the recent snow storm, it appeared to me that the roads were pretty good in the area on Sunday and definitely ok on Monday. I am not sure if you tie you decision to WCPSS or to the other Mathnasium locations though.
Our kids look forward to their sessions each week, they are always either learning new skills or reinforcing what they know, and, our son who ended last semester with a C in math and almost flunked his final exam (before starting at Mathnasium), just ended this quarter with a solid A.
My daughter came to Mathnasium towards the end of the semester...even so..just in 1 month Mathnasium was able to bring her up to speed and helped identify all her weak spots and gave her extra work to gain those skills. I am so glad I found Mathnasium for my daughter. I'm bringing her back for math 3 next year. It's totally worth it 😀
Mathnasium has been very accommodating to ensure that my daughters receive their makeup lessons in situations when they are unable to make their regular session times. Due to the fact that our daughters have hectic schedules...something always seems to come up and Mathnasium always works with me. I appreciate the effort they make to always make the necessary adjustments to the girls' tutoring schedule when extenuating circumstances present themselves.
Mathnasium is extremely organized and tutoring sessions run on time. The teacher is knowledgeable with the difficult high school material. The teacher on occasion supplied my daughter with extra study problems. Extremely helpful & accommodating on all fronts.
Truly appreciate the hard work your teachers put in to make math interesting and fun for the students .The most important aspect is to recognise the weak areas of a student and to help & coach him to face challenging problems confidently.Thank You. - Monika Joshi.
Catherine has been using Mathnasium as a learning resource for a number of years and we feel that it has been critical in her success with math. We have also noticed that as she has progressed through the grades it has become important to ensure that Mathnasium is targeted to the material being covered in her class.
Both my girls excel in math and part of it is because of mathnasium. Also, if I had an issue or the girls didn't go well with an instructor they were happy to accomodate and pair them up with another instructor.
My son has been going to Mathnasium for the past 3 years. I must say that since then he has shown great improvement in mathematics. Only one thing I would like to say is that more practice should be given and I don't prefer him jumping to the next grade math syllabus.
