# Moment of Force Converter (N·m / dyn·cm / lbf·ft / kgf·m) Convert moment of force (torque) between newton-metre (N·m, SI base), dyne-centimetre (dyn·cm, CGS = 10⁻⁷ N·m), pound-foot (lbf·ft = 1.3558179483314004 N·m), and kilogram-force-metre (kgf·m = 9.80665 N·m). Each factor is the exact product of the matching force factor and length factor. Converts via N·m to the target unit and lists all four equivalents. Reference: wheel-nut tightening torque ≈ 100 N·m, passenger-car engine peak torque ≈ 250 N·m. > Canonical page: https://elysiatools.com/en/tools/moment-of-force-converter - **Category:** Math & Numbers - **Keywords:** moment of force, torque conversion, N·m, newton-metre, dyn·cm, dyne-centimetre, CGS, lbf·ft, pound-foot, kgf·m, kilogram-force-metre, mechanical engineering ## Overview Convert moment of force or torque between N·m, dyn·cm, lbf·ft, and kgf·m. Enter a value, choose the input and output units, set the decimal places, and receive the selected conversion plus all four equivalent values. ## Inputs - **Input unit** (select) - **Value** (number): Moment of force in the selected Input unit. Can be negative (e.g. counterclockwise / loosening). - **Output unit** (select) - **Decimal Places** (number) ## When to use - Convert automotive wheel-nut torque from N·m to lbf·ft or kgf·m. - Translate torque values between SI, CGS, and force-based engineering units. - Check small theoretical physics values such as dyn·cm in N·m. ## How it works - Enter the moment of force value, including negative values for an opposite direction such as counterclockwise torque. - Select the input unit: N·m, dyn·cm, lbf·ft, or kgf·m. - Choose the output unit and specify between 0 and 10 decimal places. - The converter calculates through N·m and returns the selected result together with equivalents in all four units. ## Use cases - Automotive maintenance technicians converting wheel-nut tightening specifications. - Mechanical engineers comparing torque values across SI, CGS, and imperial units. - Physics students and researchers converting small CGS moment-of-force measurements. ## Frequently asked questions ### Which torque units does this converter support? It supports N·m, dyn·cm, lbf·ft, and kgf·m. ### What is 100 N·m in lbf·ft? 100 N·m is approximately 73.7562149 lbf·ft. ### What is the relationship between dyn·cm and N·m? 1 dyn·cm equals 0.0000001 N·m, or 10⁻⁷ N·m. ### Can I enter a negative torque value? Yes. Negative values can represent an opposite direction, such as counterclockwise or loosening torque. ### How many decimal places can I display? You can choose from 0 to 10 decimal places. ## Related tools - [Air Changes per Hour (ACH, n = Q/V)](https://elysiatools.com/en/tools/air-changes-per-hour): Compute the air change rate (ACH / n) of a room from the outdoor supply airflow Q and the room volume V: n = Q/V (1/h).
