About Gigajoule
One gigajoule is 1,000,000,000 J. Utility-scale and fuel-system reporting commonly use GJ.
About Feet-Pound
The feet-pound is a mechanical work unit common in US torque and ballistics contexts.
How to convert gigajoules to feet-pounds
1 gigajoule is equal to 7.37562149e+8 feet-pound when both are expressed in joule-equivalents:
1 gj = (1,000,000,000 J ÷ 1.3558179483314003 J) ftlb = 7.37562149e+8 ftlb
Each gigajoule is defined as 1,000,000,000 J and each feet-pound as 1.3558179483314003 J in this tool, so one gj equals 1,000,000,000 ÷ 1.3558179483314003 ftlb = 7.37562149e+8 ftlb.
Let d(gj) be the numeric amount in Gigajoule (gj), and d(ftlb) the amount in Feet-Pound (ftlb). Then:
d(ftlb) = d(gj) × (1,000,000,000 / 1.3558179483314003)
Equivalently, divide by how many gj fit into one ftlb (joules per ftlb divided by joules per gj):
d(ftlb) = d(gj) ÷ 1.35581795e-9
Or: feet-pound = gigajoule ÷ 1.35581795e-9
Examples
Example #1: Convert 1 gj to feet-pound
1 gj = 1 gj × (1,000,000,000/1.3558179483314003) ftlb = 737562149.2769999504 ftlb
1 gj = 1 gj ÷ 1.35581795e-9 = 737562149.2769999504 ftlb
Example #2: Convert 10 gj to feet-pound
10 gj = 10 gj × (1,000,000,000/1.3558179483314003) ftlb = 7375621492.7700004578 ftlb
10 gj = 10 gj ÷ 1.35581795e-9 = 7375621492.7700004578 ftlb
Summary
To convert Gigajoule to Feet-Pound, multiply the value in gj by the ratio of joules per gj divided by joules per ftlb. Equivalently: value_ftlb = value_gj × (1000000000 / 1.3558179483314003). Numerically, 1 gj equals 737562149.2772654 ftlb.
Relationship context
You are converting between SI energy (joules) (Gigajoules) and US / imperial engineering units (BTU, therm, ft·lb) (Feet-Pounds). All values are mapped through joules first. The numeric factor is 7.375621e+8.
