Poundal

What is a poundal?

The poundal (pdl) is the FPS absolute unit of force; its mass-equivalent on this scale is about 0.0141 kg.

Origin of the poundal

Defined in the foot-pound-second absolute system in the late 19th century.

Where it is used

Early 20th-century physics and engineering.

When and where it was developed

Introduced in the absolute FPS system as an alternative to gravitational units.

Scientific / Atomic

Planck Mass

What is a planck mass?

The Planck mass equals about 2.18E-8 kg, formed from the constants h-bar, c, and G.

Origin of the planck mass

Introduced by Max Planck in 1899 as part of a system of natural units.

Where it is used

Theoretical physics and quantum-gravity research.

When and where it was developed

Defined by Planck in 1899 from fundamental constants.

Poundal to Planck Mass conversion formula

Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.

The relationship between poundals and planck mass:

1 pdl = 647156.4700855878 mP
1 mP = 1.545221e-6 pdl
