To convert grams to kilograms, divide the gram value by 1,000. For example, 5,000 grams = 5,000 ÷ 1,000 = 5 kilograms. This is because there are 1,000 grams in 1 kilogram.
Mass is the amount of matter in an object and remains constant everywhere, while weight is the force of gravity acting on that mass. Mass is measured in grams, kilograms, etc., while weight is measured in newtons or pounds-force.
1 kilogram equals approximately 2.20462 pounds. To convert kilograms to pounds, multiply the kilogram value by 2.20462. To convert pounds to kilograms, divide the pound value by 2.20462.
A metric ton (tonne) equals 1,000 kilograms or 1,000,000 grams. It's equivalent to approximately 2,204.62 pounds or 1.10231 short tons (US tons).
To convert ounces to grams, multiply the ounce value by 28.3495. For example, 5 ounces = 5 × 28.3495 = 141.75 grams. One ounce is approximately 28.35 grams.
A carat is a unit of mass used for measuring gemstones and pearls. One carat equals 0.2 grams or 200 milligrams. It's the standard unit for expressing the weight of diamonds and precious stones.
