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.

Biblical / Ancient

Quadrans (Biblical Roman)

What is a quadrans (biblical roman)?

The quadrans was a quarter of an as, about 0.06 gram in this scale.

Origin of the quadrans (biblical roman)

From Latin 'quadrans', a quarter part.

Where it is used

Roman small change referenced in scripture.

When and where it was developed

A minor Roman bronze denomination.

Atomic Mass Unit to Quadrans (Biblical Roman) 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 atomic mass unit and quadranses (biblical roman):

1 u = 2.760376e-23 quadrans

1 quadrans = 3.622695e+22 u

To convert atomic mass unit to quadranses (biblical roman), multiply the value in atomic mass unit by 2.760376e-23. To reverse, multiply quadranses (biblical roman) by 3.622695e+22.

Worked examples

Example 1 — Convert 1 u to quadrans:
1 × 2.760376e-23 = 2.760376e-23 quadrans

Example 2 — Convert 100 u to quadrans:
100 × 2.760376e-23 = 2.760376e-21 quadrans

Real-world example — Spanning sub-micron to micron scale

Crossing from atomic mass unit to quadranses (biblical roman) is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 atomic mass unit translates to a much more compact value in quadranses (biblical roman) that fits the scale of biological cells and process nodes.

1000 u × 2.760376e-23 = 2.760376e-20 quadrans

Real-world example — Sub-visible-light wavelength

500 atomic mass unit (the green-yellow visible band) equals 0.5 quadranses (biblical roman) — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.

500 u × 2.760376e-23 = 1.380188e-20 quadrans
