Connect decimal representation while converting units of length with this worksheet.
How to Convert Metric Units of Length
The units of length are millimetres (mm), centimetres (cm), metres (m) and kilometres (km). The formulas for converting metric units of length are as follows:
- 1 cm = 10 mm
- 1 m = 100 cm
- 1 km = 1000 m
Being able to convert units of length allows students to better understand the scale of large distances. The distance of one kilometre is hard to visualise but one metre is much easier! Connecting one kilometre to one thousand metres helps students better understand the scale of the metric system.
In this worksheet, students are tasked with converting lengths from 1 cm up to 100 km. There are multiple answers which require the use of decimal representations.

Tips for Differentiation + Scaffolding
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 Converting Units of Measurement Posters which has the specific calculations necessary for converting units of length.
In addition to individual student work time, use this worksheet as a:
