Unit Explanations
Kilonewton MeterkNm
Source UnitA kilonewton meter (kNm) is a derived unit of torque in the International System of Units (SI), defined as the torque resulting from a force of one kilonewton applied at a distance of one meter from the axis of rotation. It quantifies the rotational force or moment about a pivot point and is essential in engineering applications. The unit is widely used in mechanical and civil engineering to describe the torque exerted by engines, motors, or other rotating systems, allowing for precise calculations in structural analyses and machinery design.
Current Use
Kilonewton meters are utilized extensively in various engineering fields, particularly in mechanical and civil engineering, to measure torque applied to shafts, beams, and other components. In automotive engineering, kNm values are critical for assessing engine performance and drivetrain efficiency. The unit is also essential in construction for analyzing the loads and moments experienced by structures under various conditions, ensuring safety and stability in design. Countries worldwide, especially those using the metric system, employ this unit in technical specifications and standards.
Fun Fact
The kilonewton meter is often used in the design of roller coasters to ensure safety while maximizing thrills.
Poundal Inchpdl·in
Target UnitThe poundal inch is a unit of moment in the foot-pound-second (FPS) system, defined as the moment created by a force of one poundal acting at a distance of one inch from the pivot point. A poundal itself is defined as the force required to accelerate a mass of one pound at the rate of one foot per second squared. Consequently, the poundal inch quantifies rotational force in a system where forces and distances are measured in pounds and inches, respectively. This unit is particularly useful in various engineering applications that require torque calculations.
Current Use
The poundal inch is primarily used in mechanical engineering and physics to quantify torque. It serves as a practical measure for evaluating the performance of rotating machinery, such as motors and gears. While not as common as the pound-foot or Newton-meter, it is still utilized in some engineering disciplines where foot-pound-second units are preferred.
Fun Fact
The poundal inch is part of the foot-pound-second system, which is less commonly used today compared to the SI system.

Definition
A kilonewton meter (kNm) is a derived unit of torque in the International System of Units (SI), defined as the torque resulting from a force of one kilonewton applied at a distance of one meter from the axis of rotation. It quantifies the rotational force or moment about a pivot point and is essential in engineering applications. The unit is widely used in mechanical and civil engineering to describe the torque exerted by engines, motors, or other rotating systems, allowing for precise calculations in structural analyses and machinery design.
History & Origin
The kilonewton meter emerged from the need to quantify rotational forces in engineering and mechanics, particularly during the 20th century as industrial machinery and design became more sophisticated. The metric system was gaining traction globally, leading to the establishment of the newton as a standard unit for force in 1889 during the first International Congress of Weights and Measures. The kilonewton, representing 1,000 newtons, was adopted to provide a more manageable scale for larger forces, particularly in fields like civil engineering and physics.
Etymology: The term 'kilonewton' derives from the prefix 'kilo-', meaning one thousand, and 'newton', named after Sir Isaac Newton, the renowned physicist who formulated the laws of motion.
Current Use
Kilonewton meters are utilized extensively in various engineering fields, particularly in mechanical and civil engineering, to measure torque applied to shafts, beams, and other components. In automotive engineering, kNm values are critical for assessing engine performance and drivetrain efficiency. The unit is also essential in construction for analyzing the loads and moments experienced by structures under various conditions, ensuring safety and stability in design. Countries worldwide, especially those using the metric system, employ this unit in technical specifications and standards.

Poundal Inch
moment • Non-SI
Definition
The poundal inch is a unit of moment in the foot-pound-second (FPS) system, defined as the moment created by a force of one poundal acting at a distance of one inch from the pivot point. A poundal itself is defined as the force required to accelerate a mass of one pound at the rate of one foot per second squared. Consequently, the poundal inch quantifies rotational force in a system where forces and distances are measured in pounds and inches, respectively. This unit is particularly useful in various engineering applications that require torque calculations.
History & Origin
The poundal inch originated from the need for a practical unit of torque in the FPS system, which was prevalent in the 19th century. The concept of torque, or moment, became essential with the advancement of machinery and engineering. The unit was devised to provide a consistent way to express rotational forces in this system, complementing the existing units of force and distance.
Etymology: The term 'poundal' combines 'pound,' a unit of force, and 'dal' derived from 'dynamical,' which relates to force and motion. The 'inch' is a standard unit of length in the imperial system.
Current Use
The poundal inch is primarily used in mechanical engineering and physics to quantify torque. It serves as a practical measure for evaluating the performance of rotating machinery, such as motors and gears. While not as common as the pound-foot or Newton-meter, it is still utilized in some engineering disciplines where foot-pound-second units are preferred.
💡 Fun Facts
- •The poundal inch is part of the foot-pound-second system, which is less commonly used today compared to the SI system.
- •In certain mechanical systems, the poundal inch can provide a more intuitive understanding of torque for engineers familiar with imperial units.
- •The concept of torque was first articulated by the physicist and engineer James Watt in the 18th century, although the poundal inch was defined later.
