    What is Torque Converter?

    Torque is a measure of rotational force. It is the tendency of a force to rotate an object about an axis.

    Understanding the Units

    Newton-meter (Nm)

    SI unit of torque.

    Common Uses: Engineering, automotive specs worldwide

    Pound-foot (lb-ft)

    Imperial unit of torque.

    Common Uses: Automotive in US, tool specifications

    Conversion: 1 lb-ft = 1.356 Nm

    Pound-inch (lb-in)

    Smaller imperial torque unit.

    Common Uses: Small fasteners, precision work

    Conversion: 1 lb-in = 0.113 Nm

    Common Torque Conversions

    Example Torque
    Wheel lug nut 100 Nm = 74 lb-ft
    Bicycle pedal 40 Nm = 29.5 lb-ft
    Family car engine peak torque 200–300 Nm = 148–221 lb-ft
    Large diesel truck engine 2,000+ Nm = 1,475+ lb-ft

    Conversion Formulas

    • Torque = Force × Distance (τ = F × r)
    • Newton-meters to pound-feet: lb-ft = Nm ÷ 1.356
    • Pound-feet to Newton-meters: Nm = lb-ft × 1.356
    • Pound-feet to pound-inches: lb-in = lb-ft × 12
    • Pound-inches to Newton-meters: Nm = lb-in × 0.1130

    Practical Examples

    Tightening a bottle cap: ~2 Nm = 1.5 lb-ft

    Spark plug: 25–30 Nm = 18–22 lb-ft torque spec

    Wheel lug nuts: 100–130 Nm = 74–96 lb-ft (varies by vehicle)

    High-performance sports car: 400+ Nm = 295+ lb-ft peak torque

    When to Use Each Unit

    Newton-meters (Nm): International specifications, scientific and engineering work
    Pound-feet (lb-ft): US automotive and mechanical tool specifications
    Pound-inches (lb-in): Small fasteners, precision instruments, electronics assembly
