Relationship Between Foot-Pound and Kilogram-Force Meter
The conversion between foot-pounds and kilogram-force meters involves converting between imperial and gravitational metric units. The foot-pound (ft·lb) is commonly used in the United States, while the kilogram-force meter (kgf·m) is a gravitational unit.
1 ft·lb = 0.138255 kgf·m
Therefore, to convert foot-pounds to kilogram-force meters, we multiply the value in foot-pounds by 0.138255.
For example, 1 foot-pound equals approximately 0.138 kilogram-force meters, and 10 foot-pounds equals approximately 1.38 kilogram-force meters.
Foot-Pound
What is a Foot-Pound (ft·lb)?
A foot-pound (symbol: ft·lb) is a unit of torque in the imperial system, representing the rotational force of one pound applied at a perpendicular distance of one foot from the axis of rotation. It equals approximately 1.35582 Newton meters. Foot-pounds are widely used in the United States for automotive, mechanical, and engineering applications.
Origin
The foot-pound has been used for centuries as a measure of work and torque in English-speaking countries. It derives from the imperial system's basic units of force (pound-force) and distance (foot). While the term 'foot-pound' can refer to both work (energy) and torque, context usually makes the meaning clear. In torque applications, it's sometimes written as 'pound-foot' (lbf·ft) to distinguish it from the energy unit, though foot-pound (ft·lb) remains more common in everyday use.
Current Use
- Automotive lug nuts (80-100 ft·lb)
- Engine cylinder head bolts (50-90 ft·lb)
- Bicycle pedals (30-35 ft·lb)
- Oil drain plugs (15-25 ft·lb)
- Various machinery fasteners
- Torque wrenches calibrated in foot-pounds
Kilogram-Force Meter
What is a Kilogram-Force Meter (kgf·m)?
A kilogram-force meter (symbol: kgf·m) is a gravitational metric unit of torque, representing the rotational force of one kilogram-force applied at a perpendicular distance of one meter from the axis of rotation. It equals approximately 9.80665 Newton meters. Kilogram-force meters are still used in some countries and industries, particularly where gravitational units remain in practice.
History and Origin
The kilogram-force meter emerged from the metric gravitational system, which was widely used before the adoption of the International System of Units (SI). It is based on the force exerted by one kilogram mass under standard gravity (9.80665 m/s²). While technically a non-SI unit, it has historical significance and continues to be used in certain regions and industries, particularly in automotive and mechanical engineering in countries transitioning to SI units.
Modern Applications
Kilogram-force meters are still used in some automotive, mechanical, and industrial applications, particularly in countries that historically used gravitational metric units. Common uses include: older automotive torque specifications, some industrial machinery documentation, mechanical engineering in transitional markets, and legacy equipment specifications. However, the unit is gradually being phased out in favor of Newton meters as part of global SI standardization. Most modern engineering and scientific work now uses Newton meters exclusively for torque measurements.
