Convert mass to weight force or solve mass or gravity with kg, pounds-mass, newtons, pounds-force, kgf, and selectable planetary gravity.

Multiply mass by the selected reference gravity.

Weight here means gravitational force magnitude, not a scale reading or apparent weight during acceleration.

Standard gravity is a convention. Planetary values are approximate reference values and vary with location; the Jupiter value excludes rotational reduction.

Mass to Weight Formula

The following equation calculates gravitational weight force from mass and gravitational acceleration.

W = M × A
  • Where W is the weight (N)
  • M is the mass (kg)
  • A is gravitational acceleration g (m/s²)

Weight is the gravitational force W = mg. It has the same mathematical form as F = ma, but g here is gravitational acceleration; an arbitrary acceleration or a scale reading is not automatically gravitational weight.

Mass to Weight Definition

Weight is actually a measure of force; it’s just described as a weight to differentiate it from other forces.

Mass to Weight Example

How to convert mass to weight

  1. First, determine the mass of the object

    Through calculations determine the actual mass of the object.

  2. Next, determine the acceleration

    Calculate or measure the acceleration on the object due to gravity. On Earth, this is 9.81 m/s^2.

  3. Calculate the weight

    Calculate the weight, also known as force, acting on the object due to gravity.

FAQ

What is weight?

Weight is the force acting on an object due to its mass and the force of gravity of a larger object.
