موضوع: اکائیوں کے مبدل

Every force unit is a fixed number of newtons, and one newton accelerates 1 kg at 1 m/s². The gravitational units use standard gravity, g₀ = 9.80665 m/s², set by the 3rd CGPM in 1901: a kilogram-force is 9.80665 N and a pound-force is 0.45359237 kg × 9.80665 m/s² = 4.4482216152605 N, both exact.

The default converts 1 kgf to 9.80665 N. Loads marked in kilograms-force or tonnes-force and climbing or lifting gear rated in kilonewtons are the usual reasons to convert: 1 kN is 101.97 kgf or 224.81 lbf.

A kilogram is a mass and a newton a force, so “1 kg = 9.81 N” holds only under standard gravity. Real gravity runs from about 9.78 m/s² at the equator to 9.83 m/s² at the poles, a spread of 0.5%.

## سوالات

### How many newtons are in a kilogram?

A mass of 1 kg weighs 9.80665 N under standard gravity, which is the definition of 1 kilogram-force. The kilogram measures mass and the newton force, so the conversion needs an acceleration; 9.80665 m/s² is the conventional value fixed in 1901, and local gravity differs from it by up to about 0.3%.

### How do I convert lbf to newtons?

Multiply by 4.4482216152605, usually rounded to 4.448. One pound-force is the weight of one pound (0.45359237 kg) under standard gravity, so the factor is exact. A 200 lbf load is 889.64 N, and 1 N is 0.224809 lbf.

### How many kgf is 1 kN?

101.97 kgf. Multiply kilonewtons by 101.9716, or divide by 0.00980665, to get kilograms-force. A carabiner marked 22 kN is rated to 2,243 kgf, or 4,946 lbf, and a 5 kN anchor to 510 kgf. The factor is exact because the kilogram-force is defined with standard gravity, 9.80665 m/s².

### What is the difference between a pound and a pound-force?

A pound (lb) is mass, 0.45359237 kg; a pound-force (lbf) is the weight of that mass under standard gravity, 4.4482216152605 N. On Earth a 10 lb object weighs about 10 lbf, which is why everyday speech uses one word for both. The poundal, 0.138255 N, is the force that accelerates 1 lb at 1 ft/s².

### How many newtons does a person weigh?

A 70 kg person weighs 686.47 N under standard gravity (70 × 9.80665), which is 70 kgf or 154.3 lbf. Bathroom scales measure this force and divide by g to display kilograms, so a scale set up for standard gravity reads about 0.3% low at the equator and 0.3% high at the poles.
