About Converting Centijoules to Decijoules
Centijoule and Decijoule 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 decijoule is 0.1 joule units.
Formula
decijoules = centijoules × 0.1
This factor comes from each unit's defined relationship to the category's base unit: 1 centijoule equals 0.01 base units, and 1 decijoule equals 0.1 base units, so dividing one by the other gives the direct centijoule-to-decijoule factor of 0.1.
Simple example
1 cJ × 0.1 = 0.1 dJ
1 centijoule = 0.1 decijoules.
Real-world example
100 cJ × 0.1 = 10 dJ
100 centijoules = 10 decijoules.
Conversion table
| Centijoule (cJ) | Decijoule (dJ) |

| 10 cJ | 1 dJ |
| 100 cJ | 10 dJ |
| 500 cJ | 50 dJ |
| 1,000 cJ | 100 dJ |
| 2,000 cJ | 200 dJ |
