About Converting Centijoules to Nanojoules
Centijoule and Nanojoule 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 nanojoule is 1e-9 joule units.
Formula
nanojoules = centijoules × 10000000
This factor comes from each unit's defined relationship to the category's base unit: 1 centijoule equals 0.01 base units, and 1 nanojoule equals 1e-9 base units, so dividing one by the other gives the direct centijoule-to-nanojoule factor of 10000000.
Simple example
1 cJ × 10000000 = 10,000,000 nJ
1 centijoule = 10,000,000 nanojoules.
Real-world example
100 cJ × 10000000 = 1,000,000,000 nJ
100 centijoules = 1,000,000,000 nanojoules.
