Enter the total mass of an object into the calculator to determine the force acting on the object due to gravity.

Weight to Force Formula

The following equation is used to calculate the Weight to Force.

F = m*a
  • Where F is the force (N)
  • m is the mass of the object (kg)
  • a is the acceleration due to gravity (9.81 m/s^2)

To calculate the force from weight, multiply the mass by the acceleration.

In this formula, the acceleration due to gravity is set as 9.81 m/s^2 for earth, but you can adjust this value in the calculator for other values.

What is Weight to Force?

Definition:

Weight to force typically refers to mass to force. Since weight is technically already a “force” on a given mass, they are equal and can’t be converted between one another.

How to Calculate Weight to Force?

Example Problem:

The following example outlines the steps and information needed to calculate Weight to Force.

First, determine the mass of the object. In this example, the mass of the object is found to be 50kg.

Next, determine the acceleration due to gravity. We will use Earth’s acceleration due to gravity of 9.81 m/s^2.

Finally, calculate the force from the weight using the formula above:

F = m*a

F = 50*9.81

F = 490.5 N

FAQ

How does the value of gravity affect the force acting on an object?

The value of gravity directly influences the force acting on an object. Since force is calculated as the product of mass and acceleration due to gravity (F = m*a), a higher gravity value increases the force, while a lower gravity value decreases the force. This is why objects weigh more on planets with higher gravity than on Earth.

Can the weight to force formula be used for objects not on Earth?

Yes, the weight to force formula can be used for objects not on Earth by adjusting the acceleration due to gravity (a) in the formula. Different celestial bodies have different gravity values, so by substituting Earth’s gravity (9.81 m/s2) with the gravity value of another planet or moon, you can calculate the force acting on an object there.

Why is weight considered a force?

Weight is considered a force because it is the result of gravity acting on the mass of an object. It is the force with which the object is pulled towards the center of the Earth or any other celestial body it is on. This force is directly proportional to the object’s mass and the acceleration due to gravity, as described by the formula F = m*a, making weight a vector quantity that has both magnitude and direction.
