About 変換先rque Conversion

変換先rque (also called moment of force) measures rotational force—the tendency of a force to cause rotation around an axis. It's the product of force and the perpendicular distance from the axis to the line of action of that force (τ = F × r). While force pushes or pulls in a straight line, torque twists or turns. Every time you turn a doorknob, tighten a bolt, or steer a car, you're applying torque.

The SI単位 is Newton meter (N·m), while automotive applications in the US often use foot-pounds (ft·lb) or the older kilogram-force meters (kgf·m). 変換先rque is crucial for specifying engine performance (determining acceleration and towing capacity), fastener specifications (preventing both loose connections and stripped threads), and any mechanical system involving rotation from bicycles to industrial robots.

Our converter handles all standard torque units for automotive, engineering, construction, and mechanical applications.

Common 変換先rque Conversions

変換先rque 単位リファレンス

Newton meter (N·m) – The SI単位 of torque, used in engineering specifications worldwide. 1 N·m = force of 1 Newton acting at 1 meter from the rotation axis. European car specifications, most industrial equipment, and scientific applications use N·m exclusively. A typical sedan engine produces 200-400 N·m peak torque.

Foot-pound (ft·lb or lb·ft) – Common in US automotive, aerospace, and construction. Force of one pound-force acting at one foot radius. Note: sometimes written lb·ft to distinguish from the ft·lb energy unit. US engine specs and torque wrench settings predominantly use ft·lb.

Kilogram-force meter (kgf·m) – Gravitational metric unit where 1 kgf·m = force from 1 kg mass due to standard gravity (9.80665 m/s²) acting at 1 meter. Common in older European and Asian specifications. Being phased out in favor of N·m but still found in legacy documentation.

Inch-pound (in·lb) – Used for smaller fasteners, electronics, and precision applications. 1 ft·lb = 12 in·lb exactly. Common in aerospace specifications, circuit board assembly, and any application where fasteners are small and over-torquing risks damage.

Newton centimeter (N·cm) – Used for small torque applications like instrument adjustments. 1 N·m = 100 N·cm exactly. Convenient for specifying torques in the 0.1-10 N·m range without decimals.

Dyne centimeter (dyn·cm) – CGS unit for very small torques in physics and laboratory settings. 1 N·m = 10⁷ dyn·cm. Appears in older physics literature and some specialized scientific instruments.
