About Converting Nanojoules to Foot-pounds
Nanojoule and Foot-pound 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 work from one pound-force over one foot.
Formula
foot-pounds = nanojoules × 7.375621e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 nanojoule equals 1e-9 base units, and 1 foot-pound equals 1.35581794833 base units, so dividing one by the other gives the direct nanojoule-to-foot-pound factor of 7.375621e-10.
Simple example
1 nJ × 7.375621e-10 = 7.375621e-10 ft-lb
1 nanojoule = 7.375621e-10 foot-pounds.
Real-world example
100 nJ × 7.375621e-10 = 7.375621e-8 ft-lb
100 nanojoules = 7.375621e-8 foot-pounds.
