eV/c² = tola × 6.542914087e+33

About Tolas

A tola is a traditional South Asian unit of mass equal to the weight of a silver rupee coin - approximately 11.664 grams. It was the standard unit for weighing gold and silver across India, Pakistan, Nepal, and Bangladesh for centuries, and remains actively used in gold jewellery markets throughout the subcontinent. Gold is routinely priced and bought in tolas at jewellers' shops (sarrafas) in India and Pakistan. A 10-tola gold bar (116.64 g) is the most popular retail gold bar size in South Asia and the Middle East.

About Electronvolt mass

In particle physics, mass and energy are interchangeable via Einstein's E = mc². The electronvolt (eV) as a mass unit equals the mass equivalent of 1 eV of energy (approximately 1.783 × 10⁻³⁶ kg). Particle masses at the subatomic scale are routinely expressed in MeV/c² or GeV/c² - the proton mass is 938.3 MeV/c², and the electron is 0.511 MeV/c². The Higgs boson, discovered at CERN in 2012, has a mass of approximately 125.25 GeV/c². This unit is exclusively used in high-energy physics and quantum field theory, where conventional mass units like grams would require impossibly small exponents.
