10 lbs to kg

How to convert 10 lbs to kg

A pound is defined as exactly 0.45359237 kilogram, so multiply:

10 lb × 0.45359237 = 4.54 kg

Dividing by 2.20462 gives the same answer. The converter above starts at 10 lb and has a second field for ounces; type a different number and the kilograms follow, or use the full lbs to kg converter. To go the other way, see kg to lbs.

10 lbs in kilograms and grams, and in stone

The 0.54 after the whole kilograms is a fraction of a kilogram: 0.5359 × 1,000 = 535.9 grams. So 10 pounds is:

• 4 kg 536 g — the way a metric scale or a parcel form reads;
• 4,536 g — in grams;
• 0.71 st — the British way of stating weight (10 ÷ 14).

The result block shows the kilograms and grams for whatever you enter, and stone from 14 lb up. 10 lb is a common size for bags of potatoes, flour and pet food, and for dumbbells. A 10 lb dumbbell weighs 4.54 kg, between the 4 kg and 5 kg dumbbells sold in metric countries.

Nearby values

From 1 to 20 lb:

Rounded for display, 10 lb is 4.5 kg on a scale with one decimal and 5 kg on one that shows whole kilograms. Going the other way, 5 kg is 11.0 lb, so a reading of 5 kg on a metric scale is 1.0 lb more than 10 lb.

10 pounds and some ounces

Scales in the U.S. often read pounds and ounces. Each ounce is 28.35 grams, so the ounces matter at this weight only in the first decimal:

10.25 lb is 10 lb 4 oz, 10.5 lb is 10 lb 8 oz and 10.75 lb is 10 lb 12 oz. Type the ounces into the second field to convert an exact reading.

A quick rule for your head

Halve the pounds, then take away 10% of that: 10 ÷ 2 = 5, and 5 − 0.5 = 4.5 kg. The rule is about 0.8% low — here 0.04 kg. Halving alone (5 kg) is 0.46 kg too high. At small weights the ounces matter more: 10 lb 8 oz is already 4.76 kg. For smaller weights, use ounces to grams.
