Units of Weight
Weight is measured in grams (g) for lighter objects like a pencil and kilograms (kg) for heavier objects like a school bag.
Units of Capacity
Capacity is the amount a container can hold, measured in millilitres (mL) for small amounts like medicine and litres (L) for large amounts like water in a bucket.
Kilogram to Gram Conversion
To convert kilograms into grams, we multiply the number of kilograms by 1000, because 1 kilogram equals 1000 grams.
Litre to Millilitre Conversion
To convert litres into millilitres, we multiply the number of litres by 1000, since 1 litre equals 1000 millilitres.
Addition and Subtraction of Quantities
We can add or subtract weights and capacities by keeping like units together (adding grams to grams and kilograms to kilograms).
