Frequently Asked Questions
What is a Newton (N)?
A Newton is the SI unit of force. 1 N is the force required to accelerate a 1 kg mass at 1 m/s². It is named after Isaac Newton. 1 N ≈ 0.2248 lbf.
What is the difference between force and weight?
Weight is a force — it is the gravitational pull on a mass. On Earth, a 1 kg mass weighs about 9.807 N (= 1 kgf). Weight changes with gravity, but mass does not.
What is kgf (kilogram-force)?
1 kgf is the force exerted by 1 kg of mass under standard gravity (9.80665 m/s²). So 1 kgf = 9.80665 N. kgf is commonly used in engineering and mechanics.
What is a dyne?
1 dyne is the force needed to accelerate 1 gram at 1 cm/s². It is a CGS unit. 1 dyne = 10⁻⁵ N. It is very small — used in surface tension measurements.
What is lbf (pound-force)?
1 lbf is the force exerted by 1 pound of mass under standard gravity. 1 lbf = 4.44822 N. It is used in the US for structural engineering, hydraulics, and aviation.
