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

Atomic Mass Unit

What is a atomic mass unit?

One unified atomic mass unit (u) is defined as 1/12 the mass of a carbon-12 atom, about 1.6605E-27 kg.

Origin of the atomic mass unit

Introduced to give atomic and molecular masses convenient numerical values.

Where it is used

Atomic, molecular, and nuclear physics and chemistry.

When and where it was developed

The unified (carbon-12) scale was adopted by IUPAC and IUPAP in 1960-1961.

Poundal to Atomic Mass Unit conversion formula

The relationship between poundals and atomic mass unit:

1 pdl = 8.483215e+24 u
1 u = 1.178798e-25 pdl

To convert poundals to atomic mass unit, multiply the value in poundals by 8.483215e+24. To reverse, multiply atomic mass unit by 1.178798e-25.

Step-by-step: convert poundals to atomic mass unit

  1. Write down the value in poundals (pdl).
  2. Multiply that value by the factor 8.483215e+24.
  3. The product is the equivalent value in atomic mass unit (u).
  4. To reverse, multiply the atomic mass unit value by 1.178798e-25.

Worked examples

Example 1 — Convert 1 pdl to u:
1 × 8.483215e+24 = 8.483215e+24 u

Example 2 — Convert 100 pdl to u:
100 × 8.483215e+24 = 8.483215e+26 u

Real-world example — Centimeter to wavelength scale

One poundal equals 10 million atomic mass unit. Physics curricula use this kind of conversion to relate everyday measurements to atomic and optical scales.

1 pdl × 8.483215e+24 = 8.483215e+24 u

Real-world example — Small-scale to atomic-scale

One poundal equals 10 million atomic mass unit — useful for physics curricula that relate everyday measurements to atomic and optical scales.

1 pdl × 8.483215e+24 = 8.483215e+24 u
