About Converting Nanojoules to Centijoules
Nanojoule and Centijoule both measure energy, and the conversion is especially useful for comparing nutrition labels (kilocalories) against scientific energy figures (joules). Specifically: Nanojoule is 1e-9 joule units, and centijoule is 0.01 joule units.
Formula
centijoules = nanojoules × 1e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 nanojoule equals 1e-9 base units, and 1 centijoule equals 0.01 base units, so dividing one by the other gives the direct nanojoule-to-centijoule factor of 1e-7.
Simple example
1 nJ × 1e-7 = 1e-7 cJ
1 nanojoule = 1e-7 centijoules.
Real-world example
100 nJ × 1e-7 = 0.00001 cJ
100 nanojoules = 0.00001 centijoules.

Frequently asked questions
How many centijoules are in 1 nanojoule?
1 nanojoule equals 1e-7 centijoules, using the exact defined conversion factor rather than an estimate.
How do I convert nanojoule to centijoule?
Multiply the nanojoule value by 1e-7. The converter above does this instantly to whatever precision you set.
How do I convert centijoule back to nanojoule?
Use the reverse factor: 1 centijoule equals 10,000,000 nanojoules. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanojoule?
Nanojoule (nJ) is a unit of energy.
What is a centijoule?
Centijoule (cJ) is a unit of energy.
Is the nanojoule to centijoule conversion exact?
Yes. Both nanojoule and centijoule are defined by fixed standards rather than physical artifacts, so the factor of 1e-7 used above is exact to as many digits as you choose to display.
