How do I convert lb·ft to N·m?

Multiply pound-feet by about 1.3558 to get newton-meters. This tool does that live — enter lb·ft on the left and read N·m on the right (or the full board).

Is lb·ft the same as ft·lb?

Yes in shop slang. Both mean foot-pounds of torque. This converter labels the unit lb·ft, which matches most US torque wrenches and dyno software.

Why does my torque wrench show N·m but the forum post shows lb·ft?

Regional tooling defaults differ. Convert before you pull — a 100 lb·ft spec is roughly 136 N·m, not 100 N·m.

Should I convert torque for aluminum vs steel fasteners the same way?

The unit math is the same. The safe clamp load is not — always use the OEM torque (and angle) for that fastener and joint, after you convert units.

lb·ft to N·m and other torque units

1 lb·ft ≈ 1.356 N·m — the factor every US/EU torque sheet cross-check needs.
Use the same units your wrench displays; guessing strips fasteners or leaves them loose.
Engine crank torque and fastener torque share units but not procedures — convert, then follow OEM steps.

US aftermarket catalogs publish crank and fastener torque in pound-feet (lb·ft). European and Japanese manuals usually list newton-meters (N·m). This torque converter gives you both instantly, plus kgf·m and lb·in for older sheets and inch-pound wrenches.

Enter the number on your dyno graph or service manual, swap units with one tap, and read the full torque board. Cookie memory keeps your last pair so the next job starts where you left off.

For critical head bolts and yield-angle fasteners, treat the conversion as math only — always finish with the OEM sequence, lubricant spec, and angle torque where required.

How to convert torque units

Enter the torque value you have. Use the figure from your wrench, manual, or dyno sheet.
Choose lb·ft, N·m, or another torque unit. Swap from/to or tap a board tile to set the result unit.
Apply the converted number carefully. Match your wrench display units, then follow the OEM torque procedure.
