MeV/c2

What is a mev/c2?

MeV/c^2 expresses mass through mass-energy equivalence, E = mc^2; 1 MeV/c^2 is about 1.783E-30 kg.

Origin of the mev/c2

Derived from Einstein's mass-energy relation, convenient for particle masses.

Where it is used

Particle physics, where masses are stated in MeV/c^2 or GeV/c^2.

When and where it was developed

Came into use with relativistic particle physics in the 20th century.

Momme

What is a momme?

The momme (mom) equals 3.75 grams.

Origin of the momme

A traditional Japanese mass unit (Japanese 'monme').

Where it is used

Pearls, and as the standard weight grade for silk fabric.

When and where it was developed

Part of the traditional Japanese shakkanho system.

MeV/c2 to Momme 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 mev/c2 and mommes:

1 MeV/c² = 4.753765e-28 mom
1 mom = 2.103596e+27 MeV/c²

Worked examples

Example 1 — Convert 1 MeV/c² to mom:
1 × 4.753765e-28 = 4.753765e-28 mom

Example 2 — Convert 100 MeV/c² to mom:
100 × 4.753765e-28 = 4.753765e-26 mom

Real-world example — From wavelengths to millimeter-scale objects

A value of one million mev/c2 sounds vast at the atomic scale but converts to a small everyday quantity in mommes — useful when relating optical-wavelength specifications to physical mounting hardware.

1000000 MeV/c² × 4.753765e-28 = 4.753765e-22 mom

Real-world example — Sub-micron to millimeter

500,000 mev/c2 converts to a small everyday quantity in mommes — useful when relating optical-wavelength specifications to physical mounting hardware.

500000 MeV/c² × 4.753765e-28 = 2.376883e-22 mom
