The conversion of 170 kg to newtons results in approximately 1664.9 newtons.
This is because weight in newtons is calculated by multiplying mass in kilograms by gravitational acceleration (about 9.81 m/s²). So, 170 kg multiplied by 9.81 gives the force in newtons, representing the weight of an object with mass 170 kg under Earth’s gravity.
Conversion Result and Explanation
170 kilograms equals roughly 1664.9 newtons. The calculation is based on Earth’s gravity, which pulls objects downward with an acceleration of 9.81 meters per second squared. This conversion helps to understand how mass translates into weight force in physics contexts.

Conversion Formula
The formula used is weight (N) = mass (kg) × acceleration due to gravity (9.81 m/s²). This works because weight is a force, and force equals mass times acceleration according to Newton’s second law. For example, multiplying 170 kg by 9.81 results in approximately 1664.9 newtons.

Conversion Definitions
kg (kilogram) is a unit of mass used to measure the amount of matter in an object, based on the International System of Units. It is a fundamental measure in physics and science, representing the quantity of matter regardless of gravity’s effects.
Newtons (N) is a force unit in the metric system, representing the force needed to accelerate a 1-kilogram mass by 1 meter per second squared. It quantifies weight or force exerted by gravity on an object in Earth’s gravitational field.
Conversion FAQs
Why does multiplying by 9.81 convert kg to newtons?
Because 9.81 m/s² is the acceleration due to gravity on Earth, multiplying mass in kg by this value calculates the force in newtons, which is the weight of the object under Earth’s gravity. This reflects how gravity influences mass to produce weight.
Can I use a different gravity value for other planets?
Yes, for planets or moons with different gravity, replace 9.81 with the local gravity value in m/s². For example, Mars has roughly 3.71 m/s², so multiplying mass by this value gives the weight on Mars. Always use the correct local gravity for accurate conversion.
What does the conversion tell me about an object’s weight?
The conversion provides the force exerted by gravity on the object, which is useful for understanding how heavy an object is in terms of force, especially for engineering, physics, or safety calculations where weight matters.
Is the conversion affected by location?
Yes, because gravity varies slightly across Earth’s surface and significantly on other celestial bodies. The standard 9.81 m/s² is an average for Earth’s surface; local gravity differences can alter the precise weight calculation.
How accurate is the conversion from kg to newtons?
The calculation is accurate assuming standard gravity of 9.81 m/s². Variations in local gravity or measurement precision of mass can introduce small errors, but for most practical purposes, it is sufficiently precise.
