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.

Scientific / Atomic

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 to MeV/c2 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 mommes and mev/c2:

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

To convert mommes to mev/c2, multiply the value in mommes by 2.103596e+27. To reverse, multiply mev/c2 by 4.753765e-28.

How to use this converter

Type a value into the calculator. The result in mev/c2 updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the MeV/c2 to Momme converter for the reverse direction.

Step-by-step: convert mommes to mev/c2

  1. Write down the value in mommes (mom).
  2. Multiply that value by the factor 2.103596e+27.
  3. The product is the equivalent value in mev/c2 (MeV/c²).
  4. To reverse, multiply the mev/c2 value by 4.753765e-28.

Worked examples

Example 1 — Convert 1 mom to MeV/c²:
1 × 2.103596e+27 = 2.103596e+27 MeV/c²

Example 2 — Convert 100 mom to MeV/c²:
100 × 2.103596e+27 = 2.103596e+29 MeV/c²

Real-world example — Centimeter to wavelength scale

One momme equals 10 million mev/c2. Physics curricula use this kind of conversion to relate everyday measurements to atomic and optical scales.

1 mom × 2.103596e+27 = 2.103596e+27 MeV/c²

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

One momme equals 10 million mev/c2 — useful for physics curricula that relate everyday measurements to atomic and optical scales.

1 mom × 2.103596e+27 = 2.103596e+27 MeV/c²
