Exact factors: 1 kg = 2.2046226218 lbs exactly | 1 kg = 35.27396195 oz | 1 stone = 6.35029318 kg | 1 lb = 453.59237 g

Understanding Weight Units

Kilogram (kg)

The SI base unit of mass, defined since 2019 by Planck's constant. Used globally in science, medicine, and trade. 1 kg = 1,000 grams = 2.2046 lbs.

Pound (lb / lbs)

Defined as exactly 0.45359237 kg since 1959. 1 pound = 16 ounces. Dominant in the US for body weight, food packaging, and shipping.

Ounce (oz)

1/16 of a pound = 28.3495 grams. Used in the US for food portions, precious metals (troy ounce = 31.1035 g), and postal weights.

Stone (st)

1 stone = 14 pounds = 6.35029 kg. Used predominantly in the UK and Ireland for body weight. A 70 kg person = 11 stone exactly.

Gram (g)

1/1,000 of a kilogram. 1 gram = 0.001 kg = 0.03527 oz. Essential for cooking, chemistry, and measuring small quantities.

Metric Ton (mt)

1 metric ton = 1,000 kg = 2,204.62 lbs. Used in international shipping, agriculture, and industrial materials. Spelled "tonne" in British English.

Exact Conversion Formulas

kg → lbs × 2.2046226218 70 kg = 154.324 lbs

lbs → kg × 0.45359237 150 lbs = 68.039 kg

kg → oz × 35.27396195 1 kg = 35.274 oz

oz → kg × 0.028349523 16 oz = 0.4536 kg

kg → grams × 1,000 1 kg = 1,000 g

g → kg ÷ 1,000 500 g = 0.5 kg

kg → stone ÷ 6.35029318 70 kg = 11.023 st

stone → kg × 6.35029318 10 st = 63.503 kg

lbs → oz × 16 5 lbs = 80 oz

oz → lbs ÷ 16 32 oz = 2 lbs

lbs → grams × 453.59237 1 lb = 453.59 g

kg → metric ton ÷ 1,000 500 kg = 0.5 mt

Note: All conversions use exact SI/NIST-defined values. The international pound was standardized to exactly 0.45359237 kg by the 1959 international agreement (USA, UK, Canada, Australia, New Zealand, South Africa).

What is the difference between a metric ton and a short ton?

1 metric ton (tonne) = 1,000 kg = 2,204.62 lbs. 1 US short ton = 2,000 lbs = 907.185 kg. 1 UK long ton = 2,240 lbs = 1,016.05 kg. The metric ton is used internationally; the short ton is used in the US.

How many kg is 100 pounds?

100 lbs × 0.45359237 = 45.359 kg. Or use the quick estimate: halve the pounds (50) and subtract 10% (5) = 45 kg — very close to the exact value.

How do I convert stone to kg?

Multiply stones by 6.35029318. Example: 11 stone × 6.35029 = 69.853 kg ≈ 70 kg. If you have stone and pounds (e.g. 11 st 4 lbs), convert the pounds to kg separately: 4 × 0.4536 = 1.814 kg, then add: 69.853 + 1.814 = 71.667 kg.
