About Converting Decijoules to Ergs
Decijoule and Erg both measure energy, and the conversion is especially useful for comparing nutrition labels (kilocalories) against scientific energy figures (joules). Specifically: Decijoule is 0.1 joule units, and an erg is a CGS energy unit.
Formula
ergs = decijoules × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 decijoule equals 0.1 base units, and 1 erg equals 1e-7 base units, so dividing one by the other gives the direct decijoule-to-erg factor of 1000000.
Simple example
1 dJ × 1000000 = 1,000,000 erg
1 decijoule = 1,000,000 ergs.
Real-world example
100 dJ × 1000000 = 100,000,000 erg
100 decijoules = 100,000,000 ergs.

Reverse conversion: Erg to Decijoule
1 erg × 0.000001 = 0.000001 dJ
1 erg = 0.000001 decijoules.
decijoules = ergs × 0.000001

Frequently asked questions
How many ergs are in 1 decijoule?
1 decijoule equals 1,000,000 ergs, using the exact defined conversion factor rather than an estimate.
How do I convert decijoule to erg?
Multiply the decijoule value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert erg back to decijoule?
Use the reverse factor: 1 erg equals 0.000001 decijoules. You can also use the swap control in the converter above to flip the direction instantly.
What is a decijoule?
Decijoule (dJ) is a unit of energy.
What is a erg?
Erg (erg) is a unit of energy.
Is the decijoule to erg conversion exact?
Yes. Both decijoule and erg are defined by fixed standards rather than physical artifacts, so the factor of 1000000 used above is exact to as many digits as you choose to display.
