Units of Weight
Weight is measured in grams (g) for lighter objects like a pencil and kilograms (kg) for heavier things like a bag of rice.
Units of Capacity
Capacity is the amount of liquid a container can hold, measured in millilitres (ml) for small amounts and litres (l) for large amounts.
Conversion of Weight
To convert kilograms to grams, multiply the number of kilograms by 1000, since 1 kg is equal to 1000 grams.
Conversion of Capacity
To convert litres to millilitres, multiply the number of litres by 1000, since 1 litre is equal to 1000 millilitres.
Addition and Subtraction of Measurements
Like numbers, you can add or subtract weights and capacities by keeping the units (g, kg, ml, l) aligned properly.
