Convert units of mass including those with decimal representation using this worksheet.

How to Convert Metric Units of Mass

The units of mass are milligrams (mg), grams (g), kilograms (kg) and tonnes (t). The formulas for converting metric units of mass are as follows:

  • 1 g = 1000 mg
  • 1 kg = 1000 g
  • 1 t = 1000 kg

When converting metric units of mass, all you need to remember is that the number 1000 is your friend! All units are multiples of 1000 unlike when converting length.

Understanding the difference between grams and kilograms can help students infer how light or heavy things would be if they are measured in milligrams or tonnes.

In this worksheet, students are tasked with converting mass measurements between units from 1 gram up to 100 tonnes. There are multiple answers which require the use of decimal representations.

An answer sheet is included with your download to make marking fast and easy!
