About Feet-Pound
The feet-pound is a mechanical work unit common in US torque and ballistics contexts.
About Megajoule
One megajoule is 1,000,000 J. It is common in fuel-content and engineering thermal calculations.
How to convert feet-pounds to megajoules
1 feet-pound is equal to 0.00000135581795 megajoule when both are expressed in joule-equivalents:
1 ftlb = (1.3558179483314003 J ÷ 1,000,000 J) mj = 0.00000135581795 mj
Each feet-pound is defined as 1.3558179483314003 J and each megajoule as 1,000,000 J in this tool, so one ftlb equals 1.3558179483314003 ÷ 1,000,000 mj = 0.00000135581795 mj.
Let d(ftlb) be the numeric amount in Feet-Pound (ftlb), and d(mj) the amount in Megajoule (mj). Then:
d(mj) = d(ftlb) × (1.3558179483314003 / 1,000,000)
Equivalently, divide by how many ftlb fit into one mj (joules per mj divided by joules per ftlb):
d(mj) = d(ftlb) ÷ 737562.14927726541646
Or: megajoule = feet-pound ÷ 737562.14927726541646
Examples
Example #1: Convert 1 ftlb to megajoule
1 ftlb = 1 ftlb × (1.3558179483314003/1,000,000) mj = 0.0000013558 mj
1 ftlb = 1 ftlb ÷ 737562.14927726541646 = 0.0000013558 mj
Example #2: Convert 10 ftlb to megajoule
10 ftlb = 10 ftlb × (1.3558179483314003/1,000,000) mj = 0.0000135582 mj
10 ftlb = 10 ftlb ÷ 737562.14927726541646 = 0.0000135582 mj
Summary
To convert Feet-Pound to Megajoule, multiply the value in ftlb by the ratio of joules per ftlb divided by joules per mj. Equivalently: value_mj = value_ftlb × (1.3558179483314003 / 1000000). Numerically, 1 ftlb equals 0.0000013558179483314003 mj.
Relationship context
You are converting between US / imperial engineering units (BTU, therm, ft·lb) (Feet-Pounds) and SI energy (joules) (Megajoules). All values are mapped through joules first. The numeric factor is 1.355818e-6.
