About Converting Decijoules to Nanojoules
Decijoule and Nanojoule 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 nanojoule is 1e-9 joule units.
Formula
nanojoules = decijoules × 100000000
This factor comes from each unit's defined relationship to the category's base unit: 1 decijoule equals 0.1 base units, and 1 nanojoule equals 1e-9 base units, so dividing one by the other gives the direct decijoule-to-nanojoule factor of 100000000.
Simple example
1 dJ × 100000000 = 100,000,000 nJ
1 decijoule = 100,000,000 nanojoules.
Real-world example
100 dJ × 100000000 = 10,000,000,000 nJ
100 decijoules = 10,000,000,000 nanojoules.

Frequently asked questions
How many nanojoules are in 1 decijoule?
1 decijoule equals 100,000,000 nanojoules, using the exact defined conversion factor rather than an estimate.
How do I convert decijoule to nanojoule?
Multiply the decijoule value by 100000000. The converter above does this instantly to whatever precision you set.
How do I convert nanojoule back to decijoule?
Use the reverse factor: 1 nanojoule equals 1e-8 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 nanojoule?
Nanojoule (nJ) is a unit of energy.
Is the decijoule to nanojoule conversion exact?
Yes. Both decijoule and nanojoule are defined by fixed standards rather than physical artifacts, so the factor of 100000000 used above is exact to as many digits as you choose to display.
