ποΈ What are Metric Units of Mass?
- Mass is measured in milligrams (mg), grams (g), kilograms (kg), and tonnes (t).
- The conversion rates you have to know: 1000 mg = 1 g, 1000 g = 1 kg, and 1000 kg = 1 t.
ποΈ How to Convert Units of Mass?
- Converting to a smaller unit means multiplying; converting to a larger unit means dividing.
- For example, 21 kg = 21000 g (multiply by 1000) and 560 kg = 0.56 t (divide by 1000).
ποΈ How to Calculate with Different Units?
- Before adding or subtracting, convert all values to the same unit.
- Choose one unit (e.g. all grams or all kilograms) and do not mix units.
