What is the SI unit for force?

The SI unit for force is the Newton. This unit is named after Sir Isaac Newton, in recognition of his work in classical mechanics, particularly his Second Law of Motion, which states that force is equal to mass times acceleration (F=ma). In this context, one Newton is defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared.

Understanding force in terms of the Newton helps to provide a standardized measure that is essential for scientific calculations and comparisons across different systems of measurement. Other units mentioned, like the kilogram, pound, and meter, refer to mass and distance rather than force, making the Newton the correct and appropriate unit for this context.
