Convert weight to force easily with our Weight to Force Calculator. Enter mass, select gravity, and get force in Newtons instantly.
Understanding the relationship between weight and force is essential in physics and engineering. Weight is the force exerted by gravity on an object, and it can be converted into force using simple calculations. Our Weight to Force Calculator makes it effortless to determine the force of an object based on its weight. Whether you're a student, engineer, or physics enthusiast, this tool will help you calculate force in Newtons using mass and gravity.
Weight and force are related through Newton’s Second Law of Motion. The weight of an object is the force due to gravity acting on its mass. This force is calculated using the formula:
Force (F) = Mass (m) × Acceleration due to Gravity (g)
Where:
This equation helps determine how much force an object experiences due to gravity.

This tool provides instant and accurate results for physics problems and engineering calculations.
Let's calculate the force of a 50 kg object on Earth:
F = 50 kg × 9.81 m/s²
F = 490.5 N
If the object were on the Moon (where g = 1.62 m/s²), the force would be:
F = 50 kg × 1.62 m/s²
F = 81 N
As you can see, weight depends on gravity, which varies depending on location.
| Mass (kg) | Gravity (m/s²) | Force (N) |
|---|---|---|
| 1 kg | 9.81 | 9.81 N |
| 10 kg | 9.81 | 98.1 N |
| 50 kg | 9.81 | 490.5 N |
| 100 kg | 9.81 | 981 N |
| 1 kg | 1.62 (Moon) | 1.62 N |
| 10 kg | 1.62 (Moon) | 16.2 N |
This table helps compare forces on Earth and the Moon based on weight.
Normal force is the perpendicular force exerted by a surface. It equals the weight of an object when resting on a flat surface. The formula is:
Normal Force (N) = Mass (m) × Gravity (g) × cos(θ)
Where θ is the angle of inclination. On a flat surface, θ = 0, so cos(0) = 1, making normal force equal to weight.
If weight is given in pounds (lbs), you can convert it to force in Newtons using:
F (N) = Weight (lbs) × 4.448
For example, if an object weighs 100 lbs:
F = 100 × 4.448 = 444.8 N
G-force is the multiple of Earth’s gravity acting on an object. It’s calculated using:
G-force = Force (N) / (Mass (kg) × 9.81 m/s²)
For example, if a 70 kg object experiences 980 N:
G-force = 980 / (70 × 9.81) = 1.42 G
This means the object experiences 1.42 times the force of gravity.
The Weight to Force Calculator is a useful tool for converting weight into force in Newtons. It simplifies calculations and helps in physics, engineering, and scientific studies. Whether you need to determine force for a physics experiment or engineering project, this calculator provides quick and precise results.
Use the formula F = m × g, where m is mass in kg and g is gravity (9.81 m/s² on Earth).
For a flat surface, normal force equals weight: N = m × g.
Multiply weight in pounds by 4.448 to get force in Newtons.
Divide force by mass × 9.81 to get the g-force.
Weight is the force exerted by gravity on an object, while force is a general term that includes other interactions like friction, tension, and applied force.
