800 newtons is approximately equal to 81.63 kilograms.
This conversion is based on the fact that weight in newtons divided by gravity gives mass in kilograms. Since weight (in newtons) equals mass (kg) times gravity (9.81 m/s²), dividing 800 newtons by 9.81 results in the mass in kg.
Conversion Result
To convert 800 newtons to kg, you divide by 9.81, which is the acceleration due to gravity. So, 800 ÷ 9.81 = 81.63 kg.

Conversion Formula
The formula to convert newtons to kilograms is: mass (kg) = weight (N) ÷ gravity (9.81 m/s²). This works because weight is a force caused by gravity acting on mass, so dividing the force by gravity gives the mass itself. For example, 500 N ÷ 9.81 ≈ 50.97 kg.
Conversion Example
- Convert 1000 N to kg:
- Step 1: Write the formula: mass = weight ÷ gravity.
- Step 2: Substitute: 1000 ÷ 9.81.
- Step 3: Calculate: 1000 ÷ 9.81 ≈ 101.94 kg.
- Convert 600 N to kg:
- Step 1: Use the formula: mass = 600 ÷ 9.81.
- Step 2: Perform division: 600 ÷ 9.81 ≈ 61.16 kg.
- Convert 1200 N to kg:
- Step 1: Formula: 1200 ÷ 9.81.
- Step 2: Calculation: 1200 ÷ 9.81 ≈ 122.30 kg.

Conversion Definitions
Newtons
Newtons (N) measure force, representing the push or pull on an object caused by gravity or other forces, calculated as mass (kg) times acceleration (m/s²). One newton is the force needed to accelerate a one-kilogram object at 1 meter per second squared.
Kg
Kilogram (kg) is a unit of mass, indicating the amount of matter in an object. It is a fundamental SI unit used worldwide to quantify the weight of objects, and is independent of gravity, unlike newtons which measure force.
Conversion FAQs
Can I convert newtons to kg directly?
Yes, but only when considering gravity. Since force in newtons equals mass times gravity, dividing newtons by 9.81 gives the mass in kg. Without gravity, the units are not directly interchangeable, because they measure different physical quantities.
What is the gravity used in most conversions?
The standard gravity used for conversions is 9.81 meters per second squared, which approximates Earth’s average gravitational acceleration at sea level. Variations in gravity can change the resulting mass calculation slightly.
How accurate is dividing force by gravity?
Dividing force by 9.81 provides a good estimate of mass under Earth’s gravity. However, local gravity variations, measurement errors, or different planetary gravities can affect the precision of this calculation.
Is there a way to convert newtons to other mass units?
Yes, you can convert force to other units like pounds-mass by first converting newtons to kilograms and then multiplying by 2.20462 (pounds per kg). Ensure you account for the gravity differences if converting force on other planets.
