Mental math trick
Double the kilograms and add 10% of the result. For 70 kg: 70 × 2 = 140, plus 14 = 154 lb. The exact answer is 154.3 lb, so the trick is extremely close.
Body weight reference
50 kg ≈ 110 lb, 60 kg ≈ 132 lb, 70 kg ≈ 154 lb, 80 kg ≈ 176 lb, 90 kg ≈ 198 lb, 100 kg ≈ 220 lb. If you track weight in both units, remember that a change of 1 kg is about 2.2 lb.
Gym and weightlifting
Olympic plates are usually 25, 20, 15, 10, 5, 2.5 and 1.25 kg. A 20 kg bar is about 44 lb, and a 20 kg plate is about 44 lb. A bar loaded with two 20 kg plates totals 60 kg, or roughly 132 lb. In US gyms, 45 lb plates are about 20.4 kg, so "a plate on each side" is slightly heavier than the metric version.
Airline luggage limits
Many airlines allow checked bags up to 23 kg (about 50 lb) in economy and 32 kg (about 70 lb) in premium cabins. Cabin bags are often limited to 7 to 10 kg (15 to 22 lb). Weigh your suitcase at home to avoid overweight fees, which can be expensive.
Cooking and shipping
Recipes and parcel services often list weights in grams or kilograms. 500 g is about 1.1 lb, and 1 lb is about 454 g. For flour, sugar and butter by volume, see our cups to grams guide.
Stones
In the UK, body weight is often given in stones. One stone is 14 lb, or about 6.35 kg. 70 kg is about 11 stone.
Why accuracy matters
For medical dosing, shipping costs and competition weigh-ins, use the precise factor rather than approximations, and round only at the end of your calculation.
