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.
