How to use the wrench torque calculator
Find the torque applied by a hand force on a wrench at a given angle. Enter hand force, wrench length, force angle to wrench in the fields above; the torque are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “wrench torque”, “spanner torque”, “how much torque from a force”, “calculate wrench torque”, “find torque”.
Formula
Variables
- F — Hand force (N)
- L — Wrench length (m)
- ang — Force angle to wrench (°)
Worked example
With hand force = 150 N, wrench length = 0.3 m, force angle to wrench = 90 °, the calculator gives torque ≈ 45 N·m; torque ≈ 33.19029 lb·ft.
Frequently asked questions
What is the wrench torque calculator used for?
Find the torque applied by a hand force on a wrench at a given angle. It helps with questions such as “wrench torque”, “spanner torque”, “how much torque from a force”.
What is the formula for the wrench torque calculation?
Torque (N·m) = F × L × sin(ang). Torque (lb·ft) = [Torque] × 0.737562. Here F is hand force (N), L is wrench length (m), ang is force angle to wrench (°).
What inputs do I need for the wrench torque calculator?
You need hand force in N, wrench length in m, force angle to wrench in °. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the wrench torque calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the wrench torque result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
