KG to LBS Converter
Type a weight in any unit, like 70 kg, 11 st 3 lb or 7 lb 8 oz, and this free converter shows it in pounds, pounds and ounces, stone and pounds, kilograms, grams and ounces at once. One pound is exactly 0.45359237 kg, so 70 kg is 154.32 lb, or 11 st 0.3 lb.
154.32 lb
= 154 lb 5.2 oz = 11 st 0.3 lb
What is a kg to lbs converter?
It turns kilograms into pounds, and any weight into every other common unit, at once. One pound is exactly 0.45359237 kg, so the decimal is simple. What a quick converter leaves out is the way people actually say weight: pounds and ounces for a newborn, stone and pounds for a person in the UK.
| Kilograms | Pounds | Stone and pounds |
|---|---|---|
| 50 kg | 110.23 lb | 7 st 12.2 lb |
| 60 kg | 132.28 lb | 9 st 6.3 lb |
| 70 kg | 154.32 lb | 11 st 0.3 lb |
| 80 kg | 176.37 lb | 12 st 8.4 lb |
| 90 kg | 198.42 lb | 14 st 2.4 lb |
| 100 kg | 220.46 lb | 15 st 10.5 lb |
How do you use it?
Type the weight with its unit. 70 kg, 154 lb, 11 st 3 lb, 7 lb 8 oz and 500 g all work. A plain number uses the unit you pick next to the box.
Read the result. A metric weight comes back in pounds, pounds and ounces, and stone and pounds. An imperial weight comes back in kilograms and grams.
Check every unit. Grams, ounces, metric tonnes, US and UK tons and troy ounces update together below.
What does it do that a quick converter doesn't?
It reads weight the way you write it: 11 st 3 lb, 11st 3 and 7 lb 8 oz convert as one weight, where most converters take one decimal number. It answers in compound units, so 3.4 kg comes back as 7 lb 7.9 oz, not 7.496 lb. And it settles the units that share a name: a plain "ton" is read as the 2,000 lb US ton, with the 2,240 lb UK ton and the 1,000 kg metric tonne shown beside it, and the troy ounce used for gold sits on its own line, about 9.7% heavier than the everyday ounce.
How do you convert a baby's weight from pounds and ounces?
Divide the ounces by 16, add them to the pounds, then multiply by 0.45359237.
| Pounds and ounces | Kilograms |
|---|---|
| 5 lb 8 oz | 2.495 kg |
| 6 lb | 2.722 kg |

| 8 lb | 3.629 kg |
| 9 lb | 4.082 kg |
What doesn't this converter do?
It doesn't interpret a weight: no BMI, no healthy range, no judgment, because those depend on far more than one number. It doesn't show gold or silver prices, which change by the minute. And it doesn't convert fluid ounces, because they measure volume; a fluid ounce of honey weighs more than one of water. If you type fl oz, it tells you so rather than guessing.
Why is a pound exactly 0.45359237 kg?
Because six countries, including the United States and the United Kingdom, agreed in 1959 on one international pound, defined as exactly 0.45359237 kg. A stone is 14 of those pounds, an ounce is one sixteenth, and a US ton is 2,000. Every number here follows from that definition, rounded only when it is displayed.
Frequently asked questions
How do I convert kg to lbs?
Multiply the kilograms by 2.20462, or divide them by 0.45359237, which is the exact size of a pound in kilograms. So 70 kg is 154.32 lb and 100 kg is 220.46 lb. To go from pounds to kilograms, multiply by 0.45359237 instead. This converter does both from one box as you type.
How do I convert kg to stone and pounds?
Convert to pounds first, then divide by 14, because a stone is 14 pounds. The whole number is stone and the remainder is pounds: 70 kg is 154.32 lb, which is 11 stone and 0.3 pounds. This converter shows stone and pounds for any weight, the way people in the UK and Ireland say body weight.
How many pounds are in a stone?
Exactly 14 pounds, which is 6.35029318 kilograms. Stone is still the everyday unit for body weight in the United Kingdom and Ireland, so 11 st 3 lb means 157 pounds, or about 71.2 kg. You can type it here exactly as you would say it, 11 st 3 lb or 11st 3, and it converts the whole thing.
How do I convert pounds and ounces to kg?
Turn the ounces into a fraction of a pound by dividing by 16, add it to the pounds, then multiply by 0.45359237. A baby weight of 7 lb 8 oz is 7.5 lb, which is 3.402 kg. In this converter you can type 7 lb 8 oz directly and it adds the parts up before converting.
Why is a pound exactly 0.45359237 kg?
Because the international yard and pound agreement, in force since July 1, 1959, defined it that way for the United States, the United Kingdom and four other countries. Before that, the American and British pounds differed very slightly. Every result on this page follows from that exact number, with no rounding until it is shown.
Is a ton 2,000 or 2,240 pounds?
Both, depending on where you are. The US ton, or short ton, is 2,000 pounds. The UK ton, or long ton, is 2,240 pounds. A metric tonne is 1,000 kilograms, about 2,204.6 pounds. This converter reads a plain "ton" as the US ton, says so on screen, and shows all three side by side.
Is an ounce of gold the same as an ounce of flour?
No. Gold, silver and other precious metals are weighed in troy ounces of 31.1034768 grams, while everyday ounces are 28.349523125 grams, so a troy ounce is about 9.7% heavier. Type 1 troy oz here to see the difference. The converter shows weights only, not metal prices, which change by the minute.
Can I convert fluid ounces to grams here?
No, because a fluid ounce measures volume, not weight. A fluid ounce of water weighs about 29.6 grams, but the same fluid ounce of honey or flour weighs something else, since it depends on the ingredient. If you type fl oz, the converter says so instead of guessing. For cups and spoons by ingredient, use the cooking converter.
Does this converter tell me if my weight is healthy?
No. It converts weight between units and nothing more: it does not calculate BMI, compare a number with a healthy range, or judge a result. A body weight means different things for different heights, ages and bodies, and that is a conversation for a doctor, not for a unit converter.
How accurate is this weight converter?
Exact to the definitions. The pound, ounce, stone, ton and troy ounce are all fixed multiples of the kilogram, so the math has no approximation, and rounding happens only when a number is shown. Pounds and ounces show ounces to one decimal, and stone and pounds show pounds to one decimal.
