About Converting Yoctojoules to Terajoules
Yoctojoule and Terajoule both measure energy, and the conversion is especially useful for comparing nutrition labels (kilocalories) against scientific energy figures (joules). Specifically: Yoctojoule is 1e-24 joule units, and terajoule is 1000000000000 joule units.
Formula
terajoules = yoctojoules × 1e-36
This factor comes from each unit's defined relationship to the category's base unit: 1 yoctojoule equals 1e-24 base units, and 1 terajoule equals 1e+12 base units, so dividing one by the other gives the direct yoctojoule-to-terajoule factor of 1e-36.
Simple example
1 yJ × 1e-36 = 1e-36 TJ
1 yoctojoule = 1e-36 terajoules.
Real-world example
100 yJ × 1e-36 = 1e-34 TJ
100 yoctojoules = 1e-34 terajoules.
