Convert Megaelectronvolt to Foot-pound
1 megaelectronvolt = 0.0000000000001181705 foot-pound (ft·lbf). For example, 10 megaelectronvolt = 0.000000000001181705 foot-pound and 100 megaelectronvolt = 0.00000000001181705 foot-pound. Type any value below to convert megaelectronvolt to foot-pound both ways — it runs entirely in your browser.
Torque vs energy: Foot-pound (ft·lbf) is used both as a unit of ENERGY — where 1 N·m = 1 joule exactly — and as a unit of TORQUE (a twisting force × distance). This page converts the ENERGY meaning, so the figures above are correct for work and heat. A newton-metre of torque is a different physical quantity and does NOT convert into joules, kilowatt-hours or calories.

How to convert Megaelectronvolt to Foot-pound
To convert megaelectronvolt to foot-pound, multiply the number of megaelectronvolt by the conversion factor 0.0000000000001181705, because 1 MeV = 0.0000000000001181705 ft·lbf. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 ft·lbf = 8,462,350,000,000 MeV, so you divide by 0.0000000000001181705 (or multiply by 8,462,350,000,000) to turn foot-pound back into megaelectronvolt.
ft·lbf = MeV × 0.0000000000001181705 ·
MeV = ft·lbf × 8,462,350,000,000
- Write down the value you want to convert, in megaelectronvolt.

Megaelectronvolt vs Foot-pound: which is bigger?
A foot-pound is the larger unit: one foot-pound equals 8,462,350,000,000 megaelectronvolts. Put another way, you need 8,462,350,000,000 megaelectronvolts to make a single foot-pound.
What is a Megaelectronvolt? History, origin and usage
The electronvolt was born from particle accelerators, where a charged particle gains energy equal to its charge times the voltage it crosses; one electronvolt is the energy an electron gains across one volt. The megaelectronvolt (one million eV) became the natural scale for nuclear and subatomic energies, and since the 2019 SI redefinition it is pinned to the exactly-defined elementary charge.
MeV is the working energy unit of nuclear and particle physics — describing radioactive decays, nuclear reaction energies, medical radiotherapy beams, and (via E = mc²) the masses of subatomic particles. A particle accelerator’s energy is quoted directly in MeV, GeV or TeV.
Because mass and energy are equivalent, particle masses are stated in MeV/c²: an electron is about 0.511 MeV/c² and a proton about 938 MeV/c². When an electron meets its antimatter partner, the positron, and annihilates, the pair yields about 1.022 MeV of energy.
What is a Foot-pound? History, origin and usage
The foot-pound is a traditional British and American unit of work, defined as the energy transferred when one pound-force acts through a distance of one foot. It predates the metric joule and grew out of practical engineering in the imperial system, where force was measured in pounds-force and distance in feet.
The foot-pound survives in US engineering and especially in firearms ballistics, where the muzzle energy of a bullet is almost always quoted in foot-pounds. Its near-twin, the pound-foot (lbf·ft), is the everyday US unit of torque for engines and fasteners.
One foot-pound is about 1.356 joules — roughly the energy needed to lift a one-pound weight one foot. The foot-pound of energy and the pound-foot of torque carry the same number but describe different quantities, so careful writers add “of energy” or “of torque” to avoid confusion.

Tips for converting Megaelectronvolt to Foot-pound
- To go from megaelectronvolt to foot-pound, multiply by 0.0000000000001181705; to go back, divide by 0.0000000000001181705 (or multiply by 8,462,350,000,000).
- For a quick mental estimate, remember that 1 megaelectronvolt ≈ 0.0000000000001181705 foot-pound, so 10 megaelectronvolt ≈ 0.000000000001181705 foot-pound.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Megaelectronvolt to Foot-pound converter
Type a number into the Megaelectronvolt field and the equivalent in Foot-pound appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Foot-pound field to convert the other way (foot-pound to megaelectronvolt). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 MeV = 0.0000000000001181705 ft·lbf), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for megaelectronvolt-to-foot-pound conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- NIST Special Publication 811 — Guide for the Use of the SI — publishes the exact metric equivalents of the customary units. The inch, foot, yard and mile are defined exactly in metres by the 1959 international yard-and-pound agreement, so every imperial figure on this page is exact, not rounded.
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
