Millinewton

Millinewton (mN) is a unit of force in the SI system, commonly used in physics and engineering disciplines. It is equal to one thousandth of a newton, the standard SI unit of force.

Definition

The millinewton is defined as the force required to accelerate a one kilogram mass by one millimeter per second squared. This is in accordance with Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

Usage

Millinewtons are often used in fields such as biomechanics and microengineering, where forces are typically small. For example, in the study of insect flight, the forces exerted by the wings are often in the order of millinewtons. Similarly, in microengineering, the forces involved in the manipulation of tiny components can also be measured in millinewtons.

Conversion

1 millinewton is equivalent to:

• 0.001 newtons
• 0.101971621 kilogram-force
• 0.224808943 pound-force
