How to convert between different metric mass?
1 kilogram (kg) = 1000 grams (g)

To convert from a larger unit to a smaller unit, we multiply.
For example, to convert 12 kilograms to grams, multiply by 1,000:
12 kilograms = 12 × 1,000 = 12,000 grams.

To convert from a smaller unit to a larger unit, we divide.
For example, to convert 17,000 grams to kilograms, divide by 1000:
7,000 grams = 7,000 ÷ 1,000 = 7 kilograms.

Find the equivalent measures.

1 kg = g

3 kg = g

kg = 4,000 g

17 kg = g

kg = 20,000 g

300 kg = g

1 kg 500 g = g

3 kg 715 g = g

17 kg 84 g = g

25 kg 9 g = g

kg g = 7,481 g

210 kg 50 g = g

kg g = 21,415 g

kg g = 2,091 g

3,715 g - 1,500 g = g

1 kg - 237 g = g

25 kg 9 g + 24 kg 991 g = g

27 kg 650 g - 20 kg 990 g = g

14 kg 505 g - 4,288 g = kg g

5 kg 658 g + 57,481 g = kg g
