Units explained
MeV/c2
MeV/c^2 expresses mass through mass-energy equivalence, E = mc^2; 1 MeV/c^2 is about 1.783E-30 kg.
Derived from Einstein's mass-energy relation, convenient for particle masses.
Particle physics, where masses are stated in MeV/c^2 or GeV/c^2.
Came into use with relativistic particle physics in the 20th century.
Quarter (UK)
The UK quarter equals one-fourth of a long hundredweight, 28 pounds (about 12.7 kg).
A 'quarter' of the hundredweight in the British imperial system.
Historical British trade in coal, grain, and agricultural goods.
Defined within the imperial hundredweight system.
MeV/c2 to Quarter (UK) conversion formula
The relationship between mev/c2 and quarters (uk):
To convert mev/c2 to quarters (uk), multiply the value in mev/c2 by 1.403606e-31. To reverse, multiply quarters (uk) by 7.124506e+30.

Step-by-step: convert mev/c2 to quarters (uk)
- Write down the value in mev/c2 (MeV/c²).
- Multiply that value by the factor 1.403606e-31.
- The product is the equivalent value in quarters (uk) (qr).
- To reverse, multiply the quarter (uk) value by 7.124506e+30.
Worked examples
Example 1 — Convert 1 MeV/c² to qr:
1 × 1.403606e-31 = 1.403606e-31 qr
Example 2 — Convert 100 MeV/c² to qr:
100 × 1.403606e-31 = 1.403606e-29 qr
Real-world example — Molecular dimensions
The diameter of small molecular structures (around 2 mev/c2) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.
2 MeV/c² × 1.403606e-31 = 2.807212e-31 qr
Real-world example — Wavelengths across the spectrum
Optical and atomic-scale phenomena are routinely cross-converted between sub-micron units. A photon of wavelength 800 mev/c2 can be re-expressed in quarters (uk) for direct comparison with another instrument's calibration data sheet.
800 MeV/c² × 1.403606e-31 = 1.122885e-28 qr
