What Is a Gram-force?
A gram-force is a unit of force equal to 0.0098067 newtons (N), the base unit for force. Force of standard gravity on 1 gram (0.00980665 N). [1]
The gram-force is classified as a metric and SI-compatible unit of force. Grams-force can be abbreviated as gf; for example, 1 gram-force can be written as 1 gf.
When working with grams-force (gf) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, grams-force (gf) are widely used across fine-tolerance laboratory, analytical, and micro-scale force measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Millinewton?
A millinewton is a unit of force equal to 1/1,000 of a newton (0.001 N). One-thousandth of a Newton. [2]
The millinewton is classified as a metric and SI-compatible unit of force. Millinewtons can be abbreviated as mN; for example, 1 millinewton can be written as 1 mN.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millinewton (mN) a convenient decimal multiple of the newton (N).
In practice, millinewtons (mN) are widely used across fine-tolerance laboratory, analytical, and micro-scale force measurements within SI metric workflows, engineering documentation, and technical data sheets.
When converting force between grams-force (gf) and millinewtons (mN), keep full floating-point precision (1 gf = 9.80665 mN; 1 mN = 0.1019716 gf) during intermediate calculations and round only the final millinewton figure to match your instrument tolerance.
