Relationship Between Inch-Pound and Newton Meter
The conversion between inch-pounds and Newton meters involves converting between imperial and SI units. The inch-pound (in·lb) is commonly used in the United States for smaller torque specifications, while the Newton meter (N·m) is the SI unit of torque.
1 in·lb = 0.112985 N·m
Therefore, to convert inch-pounds to Newton meters, we multiply the value in inch-pounds by 0.112985.
For example, 1 inch-pound equals approximately 0.113 Newton meters, and 10 inch-pounds equals approximately 1.13 Newton meters.
Inch-Pound
What is an Inch-Pound (in·lb)?
An inch-pound (symbol: in·lb) is a unit of torque in the imperial system, representing the rotational force of one pound applied at a perpendicular distance of one inch from the axis of rotation. It is commonly used for smaller torque specifications where foot-pounds would be too large, such as in electronics assembly, precision equipment, and small fasteners.
History and Origin of the Inch-Pound
The inch-pound evolved from the imperial system of measurement as a natural subdivision of the foot-pound. As manufacturing and engineering became more precise, there was a need for smaller torque units to specify tightening specifications for smaller fasteners and delicate components. The inch-pound became standard in industries requiring precision torque measurements, particularly in aerospace, electronics, and automotive applications.
Modern Applications of Inch-Pounds
- Electronics assembly (2-10 in·lb)
- Computer hard drive screws (3-6 in·lb)
- Smartphone and tablet assembly (2-5 in·lb)
- Bicycle component screws (5-25 in·lb)
- Small engine fasteners (10-50 in·lb)
- Precision instruments
Newton Meter
What is a Newton Meter (N·m)?
A Newton meter (symbol: N·m) is the SI unit of torque, representing the rotational force of one newton applied at a perpendicular distance of one meter from the axis of rotation. It is the fundamental unit for measuring torque in the International System of Units and is used worldwide for scientific and engineering calculations.
Origin and Definition
The Newton meter is derived from the SI base units: force (Newton) and distance (meter). It was established as part of the International System of Units to provide a consistent, universal standard for torque measurements. One Newton meter equals one joule (the SI unit of energy), though the two measure different physical quantities—torque is a vector while energy is a scalar.
Current Use
- Automotive engine torque (100-500 N·m)
- Industrial machinery (50-5,000 N·m)
- Bicycle components (5-50 N·m)
- Electric motors (10-1,000 N·m)
- Precision instruments (0.001-10 N·m)
- Scientific research and international engineering standards
