Definition of Joule
- Definition
- SI unit of energy: 1 J = 1 N·m = 1 kg·m²·s⁻².
- Notes
- Used universally in physics, chemistry, and engineering.

About the Kilogram-force-meter
Facts & Uses
- Legacy metric unit of work/torque defined via standard gravity: 1 kgf·m = 9.80665 J (exact, based on the conventional standard gravity gn = 9.80665 m/s²) and 9.80665 N·m.
- Handy conversions: 1 kgf = 9.80665 N; 1 kgf·m ≈ 7.233 ft·lbf; used to interpret older automotive/machinery specs.
- Aliases: meter-kilogram-force, kilopond-meter (kp·m), mkgf; common in vintage engineering tables.
- Modern standards prefer N·m (torque) and J (energy); convert kgf-based values for SI compliance.
Curiosities
- Because local gravity varies, kgf is conceptually tied to g; the exact value uses the standard gravity gn=9.80665 m/s².
- Appears on analog torque wrenches and dynamometers from pre-SI eras.
- Mix-ups happen between kgf·m (torque/work) and kg·m (moment of mass); unit symbols matter.
- In documentation, kgf·cm is also found; multiply by 0.0980665 to get N·m for modern torque specs.

About the Joule
Facts & Uses
- SI unit of energy: 1 J = 1 N·m = 1 W·s = 1 C·V = 1 Pa·m³; ubiquitous in mechanics, thermodynamics, electromagnetism, and chemistry.
- Common engineering scales: kJ, MJ, GJ for fuels, heating/cooling loads, and process energy.
- Everyday intuition: lifting ~1 N through 1 m ≈ 1 J; a 10 Wh battery stores ≈ 36,000 J for devices/IoT.
- Key links: 1 kWh = 3.6 × 10⁶ J; 1 eV = 1.602176634×10⁻¹⁹ J (exact) via the fixed elementary charge.
Curiosities
- Joule heating (I²R) connects electrical losses to thermal energy in conductors and electronics.
- Although both use N·m, torque (vector, moment) and energy (scalar, work) are physically distinct.
- Compression/expansion work in gases is often expressed as Pa·m³ (= J), linking pressure–volume integrals to energy.
- Named for James P. Joule, who quantified the mechanical equivalent of heat, bridging thermal and mechanical domains.
