Units of Weight (Mass)
We use grams (g) to weigh light objects like a pencil and kilograms (kg) to weigh heavy objects like a school bag.
Conversion of Weight
1 kilogram is equal to 1000 grams. To convert kg to grams, we multiply by 1000.
Units of Volume (Capacity)
We use milliliters (ml) to measure small amounts of liquid like medicine and liters (l) for large amounts like buckets of water.
Conversion of Volume
1 liter is equal to 1000 milliliters. To convert liters to milliliters, we multiply the number of liters by 1000.
Addition and Subtraction of Measurements
We can add or subtract weights and volumes only when they are in the same unit, either both in grams or both in kilograms.
