Convert Millimeters, Centimeters, Meters and Kilometers
Written by Adi Ackerman, Head Teacher
"Convert Millimeters, Centimeters, Meters and Kilometers" is written for 6th Grade (Ages 11-12), and it covers Common Core 6.RP.A.3.D. If your student is a year younger but already steady on measurement, the page still works. You may just need to read the instructions out loud. And if they are older and convert metric units never quite stuck, this is a short review rather than busywork.
6th grade math worksheet: convert 20 metric lengths among mm, cm, m and km, like 470 mm to cm and 13 km to meters. Answer key included. Part of our convert metric units measurement collection. Aligned to Common Core standards.
How do I use this worksheet?
Have students say how many places the decimal point moves before they write each answer. Use the whole number pages before the decimal pages.
What students will practice
- Students will convert 20 metric lengths with 10 mm = 1 cm, 100 cm = 1 m and 1,000 m = 1 km.
- Students will convert to smaller units, such as 8 m to 8,000 mm.
- Students will convert to larger units, such as 13,000 mm to 13 m and 24,000 m to 24 km.

Have students say how many places the decimal point moves before they write each answer. Use the whole number pages before the decimal pages.
What does this worksheet teach?
⌄
Convert 20 metric lengths among mm, cm, m and km, like 470 mm to cm and 13 km to meters. The directions on the page read: Use the facts in the box to convert each amount. An answer key is included.
Can I use this convert metric units worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 6th Grade measurement, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with convert metric units. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.
How do you convert metric units?
⌄
Multiply to go to a smaller unit and divide to go to a larger one, using 10, 100 or 1,000. 8 m = 8,000 mm, and 1,500 cm = 15 m.
How do you convert grams to kilograms?
⌄
Divide by 1,000, which moves the decimal point 3 places to the left. 7,400 g = 7.4 kg and 338 g = 0.338 kg.
How do you convert mixed amounts like 7 kg 350 g?
⌄
Change the larger unit and add the smaller one. 7 kg 350 g = 7,000 + 350 = 7,350 g, and 4 L 550 mL = 4,550 mL.
