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

Carbon-12 Atom Mass

What is a carbon-12 atom mass?

The mass of a single carbon-12 atom is exactly 12 u by definition, about 1.9926E-26 kg.

Origin of the carbon-12 atom mass

The reference nuclide that defines the unified atomic mass scale.

Where it is used

The defining standard for the atomic mass unit.

When and where it was developed

Chosen as the mass standard by IUPAC and IUPAP in 1960-1961.

Poundal to Carbon-12 Atom Mass conversion formula

The relationship between poundals and carbon-12 atom mass:

1 pdl = 7.069351e+23 C-12
1 C-12 = 1.414557e-24 pdl

Worked examples

Example 1 — Convert 1 pdl to C-12:
1 × 7.069351e+23 = 7.069351e+23 C-12

Example 2 — Convert 100 pdl to C-12:
100 × 7.069351e+23 = 7.069351e+25 C-12

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

One poundal equals 10 million carbon-12 atom mass — useful for physics curricula that relate everyday measurements to atomic and optical scales.

1 pdl × 7.069351e+23 = 7.069351e+23 C-12

Real-world example — Centimeter to wavelength scale

One poundal equals 10 million carbon-12 atom mass. Physics curricula use this kind of conversion to relate everyday measurements to atomic and optical scales.

1 pdl × 7.069351e+23 = 7.069351e+23 C-12
