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.

Force / Engineering

Ton (assay) (US)

What is a ton (assay) (us)?

The assay ton (US) equals about 29.167 grams, a mining-assay convenience unit.

Origin of the ton (assay) (us)

Devised so an assay sample's metal in milligrams reads as troy ounces per short ton.

Where it is used

Ore assaying and metallurgy.

When and where it was developed

Adopted in assay laboratories to simplify ore-grade calculation.

MeV/c2 to Ton (assay) (US) conversion formula

The relationship between mev/c2 and tons (assay) (us):

1 MeV/c² = 6.111983e-29 AT
1 AT = 1.63613e+28 MeV/c²

To convert mev/c2 to tons (assay) (us), multiply the value in mev/c2 by 6.111983e-29. To reverse, multiply tons (assay) (us) by 1.63613e+28.

How to use this converter

Type a value into the calculator. The result in tons (assay) (us) updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Ton (assay) (US) to MeV/c2 converter for the reverse direction.

Step-by-step: convert mev/c2 to tons (assay) (us)

  1. Write down the value in mev/c2 (MeV/c²).
  2. Multiply that value by the factor 6.111983e-29.
  3. The product is the equivalent value in tons (assay) (us) (AT).
  4. To reverse, multiply the ton (assay) (us) value by 1.63613e+28.

Worked examples

Example 1 — Convert 1 MeV/c² to AT:
1 × 6.111983e-29 = 6.111983e-29 AT

Example 2 — Convert 100 MeV/c² to AT:
100 × 6.111983e-29 = 6.111983e-27 AT

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 tons (assay) (us) — useful when relating optical-wavelength specifications to physical mounting hardware.

1000000 MeV/c² × 6.111983e-29 = 6.111983e-23 AT

Real-world example — Sub-micron to millimeter

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

500000 MeV/c² × 6.111983e-29 = 3.055992e-23 AT
