How do you calculate gravitational weight from mass?

Gravitational force (weight in Newtons) equals mass (m in kg) multiplied by local acceleration due to gravity (g in m/s²): F = m × g. On Earth (g = 9.80665 m/s²), a 100 kg object exerts approximately 980.67 Newtons (220.46 lbf).

How much does an object weigh on the Moon vs. Earth?

Moon surface gravity is approximately 1.622 m/s² (about 16.5% of Earth gravity). A 100 kg object that weighs 980.7 N (220.5 lbf) on Earth weighs only 162.2 N (36.5 lbf) on the Moon.

How to Convert Centimeter/second² to Gal

Converting Centimeter/second² (cm/s²) to Gal (Gal) is a core calculation in Linear Acceleration, which measures the temporal rate of change of an object's velocity with respect to time. Both units share an identical 1:1 scale equivalence within this physical measurement domain. They represent the exact same physical magnitude under different metrological designations or derived SI formulations (1 cm/s² ≡ 1 Gal). Any quantity expressed in Centimeter/second² translates directly to Gal without mathematical scaling.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (meter per second squared (m/s²)) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 cm/s² = 0.01 meter per second squared (m/s²)

2. Target SI Bridge (k_target):1 Gal = 0.01 meter per second squared (m/s²)

Step-by-step substitution for Centimeter/second² → Gal:V(Gal) = V(cm/s²) × ( 0.01 / 0.01 ) = V(cm/s²) × 1

Mathematical FormulaValue in Gal = Value in Centimeter/second² × 1Direct computational formula applied for standard conversion.

Worked Example

To convert 120 Centimeter/second² (cm/s²) to Gal (Gal): multiply 120 by 1 to get 120 Gal. At an industrial engineering scale, 240 cm/s² converts to 240 Gal.

Inverse check: 1 Gal = 1 cm/s².
