Gram-Force Meter [gf·m]

Gram-force meter (gf·m) is a unit of torque or moment of force that measures the rotational force produced when a force of one gram-force (gf) is applied at a distance of one meter (m) from a pivot point. This unit is often used in mechanical engineering, precision instrumentation, and scientific research where moderately small torque values need to be measured or specified.

Although the newton-meter (N·m) is the SI standard unit of torque, the gram-force meter is still useful in certain contexts, particularly when forces are expressed in gram-force due to traditional or practical reasons. The gf·m allows for torque measurements in applications involving moderate force levels but requiring a metric unit of length that is larger than centimeters or millimeters.

To put it in perspective, 1 gf·m equals approximately 9.80665 × 10⁻³ newton-meters. This unit can be handy in calibrating instruments or testing devices that operate within low to medium torque ranges, bridging the gap between small-scale and larger-scale torque measurements.

Pound-Force Foot [lbf·ft]

Pound-force foot (lbf·ft) is a unit of torque or moment of force commonly used in the United States and other countries that employ the imperial system. It measures the rotational force applied at a distance of one foot from a pivot point. Specifically, it represents the torque produced when a force of one pound-force (lbf) is applied perpendicular to a lever arm that is one foot (ft) long.

This unit is widely used in mechanical engineering, automotive industries, and machinery design to quantify twisting forces that cause rotation. For example, when tightening bolts, the torque applied is often specified in lbf·ft to ensure proper fastening without over-tightening. Similarly, engine torque ratings are frequently expressed in pound-force feet, indicating the rotational force an engine can generate.

While the SI unit of torque is the newton-meter (N·m), lbf·ft remains popular in practical applications within the imperial system due to familiarity and ease of use. To convert, 1 lbf·ft equals approximately 1.356 N·m.
