The newton (N) is the SI unit of force. 1 N = force to accelerate 1 kg mass at 1 m/sĀ².
Formula: F = ma (Force = mass Ć acceleration)
Conversions:
- 1 N = 0.225 lbf (pounds-force)
- 1 N = 0.102 kgf (kilogram-force)
- 1000 N = 1 kN (kilonewton)
Gram-force (gf) is the force exerted by one gram of mass under standard gravity (9.80665 m/sĀ²).
Formula: 1 gf = 1 gram Ć 9.80665 m/sĀ²
Conversions:
- 1 gf = 0.00980665 N (newtons)
- 1 gf = 9.80665 mN (millinewtons)
- 1 gf = 980.665 dynes
- 1 gf = 0.001 kgf (kilogram-force)
- 1 gf = 0.00220462 lbf (pounds-force)
- 1 gf = 0.035274 ozf (ounce-force)
Note: The Newton is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Gram-force belongs to the metric (SI) system.
History of the Newton and Gram-force
Named after Isaac Newton who formulated F = ma in 1687. Adopted as SI unit in 1948.
Gram-force emerged from the metric gravitational system of units, which was widely used in continental Europe before the adoption of SI units. The unit is also known as "gram-weight" or "pond" (from the Latin word for weight). While it remains in common use for consumer scales, spring specifications, and small mechanical devices, scientific and engineering applications increasingly prefer SI units like millinewtons. The gram-force is particularly persistent in industries like watchmaking, jewelry, and precision instruments where tradition and existing equipment favor its continued use.
Common Uses and Applications: newtons vs grams-force
Explore the typical applications for both Newton (imperial/US) and Gram-force (metric) to understand their common contexts.
Common Uses for newtons
Engineering: Structural loads, material testing, mechanical design.
Physics: All force calculations, dynamics, statics.
Automotive: Braking force, thrust, suspension loads.
Aerospace: Rocket thrust, lift, drag forces.
When to Use grams-force

Watchmaking: Mainspring tension specifications (typically 50-500 gf).
Jewelry: Measuring clasp strength and chain durability.
Mechanical Engineering: Small spring constants, contact force specifications.
Consumer Products: Kitchen scales, postal scales, fishing line strength.
