Poundal (pdl)

The poundal (pdl) is a unit of force in the foot-pound-second (FPS) system of measurement. It is defined as the force required to accelerate a one-pound mass by one foot per second squared. In other words,

1 poundal = 1 lb × 1 ft/s².

The poundal is much smaller than the more commonly used pound-force (lbf). It’s mainly used in some engineering contexts and classical mechanics problems where the FPS system is preferred. However, it is less common than the SI unit of force, the newton.

Conversion:

1 poundal ≈ 0.13825 newtons.

Planck Mass

The Planck mass is a fundamental physical constant in theoretical physics, representing a natural unit of mass based on fundamental constants: the speed of light, gravitational constant, and Planck’s constant.

Its value is approximately 2.18 × 10⁻⁸ kilograms (about 22 micrograms).

The Planck mass is significant in quantum gravity and string theory, marking a scale where quantum effects of gravity become strong and classical physics breaks down.
