Pennyweight (pwt)

The pennyweight (pwt) is a unit of mass traditionally used in the precious metals and jewelry industries. It is part of the troy and apothecary weight systems.

One pennyweight equals 1/20 of a troy ounce, or 24 grains, which is approximately 1.555 grams.

Pennyweights are commonly used to measure gold, silver, and gemstones, offering a precise small-scale weight unit for valuable materials.

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.
