Ergs to Joules Converter

1 erg (erg) equals 1 × 10-7 joules (J).

Quick answer

  • 1 erg = 1 × 10-7 joules
  • 1 joule = 10,000,000 ergs
  • Formula: J = erg × 1 × 10-7

1 erg = 1 × 10-7 joules

How to convert ergs to joules

J = erg × 1 × 10-7

To convert ergs to joules, multiply the number of ergs by 1 × 10-7.

Example: 10 erg to J

  1. Start with the value in ergs: 10 erg.
  2. Multiply by 1 × 10-7: 10 × 1 × 10-7 = 0.000001.
  3. Result: 10 ergs = 0.000001 joules.

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