Weight Converter
Convert any weight or mass between metric and imperial units — kilograms, grams, milligrams, tonnes, quintals, pounds, ounces and stones — with every unit shown side by side.

How It Works
Weight (technically mass) converters use the gram as the base unit and give every other unit an exact factor: 1 kilogram = 1,000 g, 1 tonne = 1,000,000 g, 1 pound = 453.59237 g, 1 ounce = 28.349523125 g, and 1 stone = 6,350.29 g. Conversion multiplies the value by the from-unit factor to reach grams, then divides by the to-unit factor. In everyday use, "weight" and "mass" are used interchangeably — mass is the amount of matter (constant everywhere), while weight is the force of gravity on that mass; on Earth the two track each other, so kilograms and pounds are used for both. India uses the metric system officially, with the quintal (100 kg) common in agriculture and the tonne in bulk trade, while pounds and ounces appear in fitness and imported goods.
Formula
Result = value × (grams per from-unit) ÷ (grams per to-unit). Base unit: gram. Exact: 1 lb = 453.59237 g, 1 oz = 28.349523125 g, 1 kg = 1000 g.
Frequently Asked Questions
How many grams are in a pound?
Exactly 453.59237 grams. A pound has 16 ounces, and 1 ounce = 28.35 g. So 1 lb = 16 × 28.35 ≈ 453.6 g.
How do I convert kilograms to pounds?
Multiply kilograms by 2.20462. For example, 70 kg = 70 × 2.20462 ≈ 154.3 lb. To convert pounds to kilograms, divide by 2.20462 (or multiply by 0.453592).
What is a quintal?
A quintal equals 100 kilograms and is widely used in Indian agriculture and commodity markets to price crops like wheat, rice and sugarcane. 10 quintals = 1 tonne.
Is weight the same as mass?
Strictly, no — mass measures the amount of matter (kilograms) and is constant everywhere, while weight is the gravitational force on that mass (newtons). In daily life on Earth they are proportional, so we use kg and lb for both.
How many ounces are in a kilogram?
1 kilogram ≈ 35.274 ounces. Since 1 kg = 1,000 g and 1 oz = 28.35 g, dividing gives about 35.27 oz.
