Torque Converters
Convert between torque units used in engineering, automotive fastener specs, drivetrain calculations, and machine design. This hub treats torque as rotational force (moment) and applies exact multiplicative factors anchored to newton-meters.
Scope & Verification
This hub groups related converter families so you can move from the category level to exact routes with one clear basis per page.
- Families are split so exact-factor, profile-based, density-based, and estimate-style pages do not collapse into one generic answer.
- Leaf pages keep calculator, common values, FAQ, and reverse routes aligned to the same assumption.
- Methodology and verification pages document how those assumptions are chosen and checked.

Conversions in this hub are represented by the canonical torque family and its registered source and target units.
Its 20 published directions use the same canonical engine through the website, JSON API, OpenAPI and WebMCP.
API & Agent documentationExplanation
Torque is the rotational effect of force applied at a distance from an axis (moment). This hub normalizes every factor through newton-meters (N·m) to keep mirror conversions stable and reversible. Included units span SI (N·m), imperial/US customary (lbf·ft, lbf·in), and metric gravimetric forms (kgf·m, kgf·cm). All relationships are fixed multiplicative scale changes with no additive offsets.
Torque converters are grouped into directional families so each leaf keeps one stable conversion model.
Open a family hub to reach leaf pages with direct answers, calculator output, and reverse links built on the same constants.
Questions & answers
Frequently Asked Questions
What is torque?
Torque is rotational force (moment), defined as force applied at a distance from an axis.
What is the SI unit of torque?
The SI unit is the newton-meter (N·m).
Are torque conversions multiplicative?
Yes. These conversions are purely multiplicative with no additive offsets.
How are lbf·ft and lbf·in related?
Exactly: 1 lbf·ft = 12 lbf·in.
