Convert newtons to lbs
Please provide values below to convert newton [N] to pound-force [lbf], or vice versa.
Newton
Definition: The newton (symbol: N) is the SI (International System of Units) derived unit of force. It is defined as 1 kilogram·meter/second2.
History/origin: The unit newton is named after Isaac Newton for his contribution to classical mechanics – particularly his second law of motion, which states that the rate of change of momentum of a body is directly proportional to the applied force, and that this change in momentum occurs in the direction of the applied force.
Current use: As an SI derived unit of force, the newton is the preferred unit of force, and is widely used in scientific contexts, particularly in physics. In everyday use, units such as the pound-force are sometimes used in place of newtons in countries like the United States.
Pound-force
Definition: The pound-force (symbol: lbf) is a unit of force used in the English Engineering System and the British Gravitational System. It is defined as the gravitational force exerted on a mass of one avoirdupois pound under the condition of standard gravity (9.80665 m/s2). Under this definition, with mass in terms of slugs, one pound-force is equal to 1 slug·foot/second2.
History/origin: The pound-force is part of the foot-pound-second (FPS) system of units. Until 1901, when the General Conference of Weights and Measures adopted a standard acceleration due to gravity of 9.80665 m/s2, the pound-force was not precisely defined.
Current use: After the adoption of the International System of Units (SI), the newton, an SI derived unit of force, became the preferred unit of measurement of force. Although the pound-force may still be used in certain contexts, it is not a widely used unit of measurement.

How to Convert Newton to Pound-force
1 N = 0.2248089431 lbf
1 lbf = 4.4482216153 N
Example: convert 15 N to lbf:
15 N = 15 × 0.2248089431 lbf = 3.3721341465 lbf
