Pounds and ounces
In the US and UK, small weights like a baby's are given in pounds and ounces. 1 lb = 16 oz. To split a decimal result: 7.05 lbs is 7 lbs plus 0.05 × 16 = 0.8 oz. In the UK, body weight is often given in stones: 1 stone = 14 lbs = 6.35 kg. You can pick ounces and stones in the Unit Converter.
Where the conversion comes up
- Flights: baggage allowances appear in kg on Indian and most Asian airlines and in lbs on US carriers.
- Gym and fitness: many gyms have plates in lbs, while Indian scales show kg.
- Shopping from the US: product weights and shipping rates are often listed in pounds.
- Medical and visa forms: US forms ask for weight in pounds.
How precise should the answer be?
Bathroom scales are accurate to about 0.1 kg, so one decimal place in pounds is enough for body weight. For shipping, round up, because couriers charge for every started pound or half kilo. For medicine doses, always use the unit on the prescription rather than converting.
