About Converting Centijoules to Ergs
Centijoule and Erg both measure energy, and the conversion is especially useful for comparing nutrition labels (kilocalories) against scientific energy figures (joules). Specifically: Centijoule is 0.01 joule units, and an erg is a CGS energy unit.
Formula
ergs = centijoules × 100000
This factor comes from each unit's defined relationship to the category's base unit: 1 centijoule equals 0.01 base units, and 1 erg equals 1e-7 base units, so dividing one by the other gives the direct centijoule-to-erg factor of 100000.
Simple example
1 cJ × 100000 = 100,000 erg
1 centijoule = 100,000 ergs.
Real-world example
100 cJ × 100000 = 10,000,000 erg
100 centijoules = 10,000,000 ergs.

Reverse conversion: Erg to Centijoule
1 erg × 0.00001 = 0.00001 cJ
1 erg = 0.00001 centijoules.
centijoules = ergs × 0.00001

Frequently asked questions
How many ergs are in 1 centijoule?
1 centijoule equals 100,000 ergs, using the exact defined conversion factor rather than an estimate.
How do I convert centijoule to erg?
Multiply the centijoule value by 100000. The converter above does this instantly to whatever precision you set.
How do I convert erg back to centijoule?
Use the reverse factor: 1 erg equals 0.00001 centijoules. You can also use the swap control in the converter above to flip the direction instantly.
What is a centijoule?
Centijoule (cJ) is a unit of energy.
What is a erg?
Erg (erg) is a unit of energy.
Is the centijoule to erg conversion exact?
Yes. Both centijoule and erg are defined by fixed standards rather than physical artifacts, so the factor of 100000 used above is exact to as many digits as you choose to display.
