How to Convert Metric Units of Length

The formulas for converting metric units of length are as follows:

• 1 cm = 10 mm
• 1 m = 100 cm
• 1 km = 1,000 m

Converting units of length allows students to understand the scale of large distances better. The distance of one kilometre is hard to visualize, but one metre is much easier! Connecting one kilometre to one thousand meters helps students better understand the scale of the metric system.

In this set of printable conversion worksheets, students are tasked with converting lengths from 1 cm to 100 km. Multiple answers require the use of decimal representations.

An answer key is included with your download to make grading fast and easy!

Scaffold & Differentiate Your Measurement Lessons

Task students who require an additional challenge with measuring objects within the classroom and determining their length in all four units featured in the worksheet. Then, have them choose the most appropriate unit for the measurement.

Students who need extra support can refer to the Converting Units of Measurement Posters, which have the specific calculations necessary to convert units of length.
