Introducing the Torque Converter — 12 Units, Instant Results

Torque specs are everywhere in automotive and mechanical engineering work — engine output in N·m, fastener specs in lbf·ft, small motor specs in ozf·in, vintage documentation in kgf·m. The new Torque Converter handles all of them in one place.

What it does

• 12 torque units: the full set across three families — SI prefixed (N·m, kN·m, dN·m, cN·m, mN·m, µN·m), Imperial force (lbf·ft, lbf·in, ozf·in), and metric-force (kgf·m, kgf·cm, gf·cm).
• All normalised through N·m: every unit converts through newton-metres as the internal reference, using exact SI-defined factors. No rounding errors accumulate through intermediate conversions.
• Swap button: reverse the conversion direction instantly without retyping.
• Full conversion table: see your value expressed in all 12 units simultaneously, so you can read off any target unit at a glance.
• Quick automotive presets: one-click access to common torque values — wheel lug nuts, spark plugs, oil drain plugs, and engine output ranges — to give you an immediate sense of scale.

Who it is for

The converter is built for three primary audiences. Automotive mechanics working across European and American service documentation need N·m to lbf·ft conversions constantly — European workshop manuals use N·m, American torque wrenches are often calibrated in lbf·ft. The converter handles this in both directions.

Mechanical engineers reading older technical literature encounter kgf·m in Soviet-era, Japanese, and pre-SI European documentation. The kgf·m and kgf·cm units are fully supported alongside the modern SI equivalents.

Robotics and electronics engineers working with small servo motors, stepper motors, and micro-mechanisms see torque specified in ozf·in or gf·cm. These small-scale Imperial and metric-force units are included alongside the larger automotive units.
