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.
Tola
The tola equals 180 troy grains, about 11.6638 grams (three-eighths of a troy ounce).
From Sanskrit 'tula', meaning a balance or weighing.
The primary unit for gold and silver across India, Pakistan, and Nepal.
Fixed at 180 grains under British India in 1833.

Real-world example — Sub-micron to millimeter
500,000 mev/c2 converts to a small everyday quantity in tolas — useful when relating optical-wavelength specifications to physical mounting hardware.
500000 MeV/c² × 1.528371e-28 = 7.641855e-23 tola
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 tolas — useful when relating optical-wavelength specifications to physical mounting hardware.
1000000 MeV/c² × 1.528371e-28 = 1.528371e-22 tola
