How many newtons is a 10 kg mass? About 98.1 N at standard gravity

Engineering calculators (Beta)

Match the diagram conditions, then follow the example inputs and results. Change numerical values in the calculator.

1. Match the diagram to your question

Distinguish mass m from downward gravitational force W.

Blue marks inputs; orange marks outputs. These diagrams explain the fixed example below; dimensions and deformation are not drawn to physical scale.

2. Example inputs

Mass m What goes here? This is mass, including fixtures or loads that move with it where required. Kilograms describe mass; newtons describe force.	10 kg

These are fixed teaching inputs. Coefficients, properties and comparison limits are not recommendations. Enter your conditions in the calculator.

3. Results for this example

Weight at standard gravity: 98.0665 N

A 10 kg mass has about 98.1 N of weight at standard gravity. This static weight excludes lifting acceleration and friction.

In the calculator results, expand “Details and intermediate values” and read “Weight at standard gravity”. For weight alone, enter the mass; speed and height can stay at zero.

4. Which formula is used?

W = mg = 10 × 9.80665 ≈ 98.1 N

Table units are not always the units required in the formula. The calculator converts selected units to its internal base units before computing.

Assumptions and exclusions

Translational motion in uniform gravity. Rotation, aerodynamic drag and losses are excluded.

“Try these example inputs” loads the fixed example. “Enter your own conditions” opens the calculator normally.

質量と重量の早見表

1kg・5kg・10kgなどの重量をNで見比べる

標準重力加速度g₀ = 9.80665 m/s²での重量
質量m	重量W = mg₀
1 kg	9.80665 N
5 kg	49.03325 N
10 kg	98.0665 N
20 kg	196.133 N
50 kg	490.3325 N
100 kg	980.665 N

この表は質量に標準重力加速度を掛けた値です。kgは質量、Nは力なので、条件なしに同じ量として換算するものではありません。kgfは別の力の単位で、1 kgf = 9.80665 Nです。

実際の場所の重力や、持ち上げる加速度・摩擦を含める場合は条件が変わります。自分の数値は、このページの「自分の条件を入力する」から計算できます。

Mass and weight reference table

Compare the weight of 1 kg, 5 kg, 10 kg and other masses

Weight at standard gravity g₀ = 9.80665 m/s²
Mass m	Weight W = mg₀
1 kg	9.80665 N
5 kg	49.03325 N
10 kg	98.0665 N
20 kg	196.133 N
50 kg	490.3325 N
100 kg	980.665 N

The table multiplies mass by standard acceleration of gravity. Kilograms measure mass and newtons measure force; they are different quantities. The kilogram-force (kgf) is a separate force unit: 1 kgf = 9.80665 N.

Local gravity, lifting acceleration and friction require different conditions. Use “Enter your own conditions” on this page for your own values.
