Ergs to Kilojoules Converter

1 erg (erg) equals 1 × 10-10 kilojoules (kJ).

Quick answer

  • 1 erg = 1 × 10-10 kilojoules
  • 1 kilojoule = 10,000,000,000 ergs
  • Formula: kJ = erg × 1 × 10-10

1 erg = 1 × 10-10 kilojoules

How to convert ergs to kilojoules

kJ = erg × 1 × 10-10

To convert ergs to kilojoules, multiply the number of ergs by 1 × 10-10.

Example: 10 erg to kJ

  1. Start with the value in ergs: 10 erg.
  2. Multiply by 1 × 10-10: 10 × 1 × 10-10 = 1 × 10-9.
  3. Result: 10 ergs = 1 × 10-9 kilojoules.

Going the other way, 1 kilojoule = 10,000,000,000 ergs, so to convert kilojoules back to ergs you divide by the same number. See kilojoules to ergs.
