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.
Kilogram-force square second/meter
The kilogram-force second-squared per meter (the hyl or TME) is about 9.807 kg.
The mass unit of the metric gravitational (technical) system.
Older continental European engineering practice.
Used in the metric technical system before SI adoption.

Worked examples
Example 1 — Convert 1 MeV/c² to hyl:
1 × 1.817809e-31 = 1.817809e-31 hyl
Example 2 — Convert 100 MeV/c² to hyl:
100 × 1.817809e-31 = 1.817809e-29 hyl
Real-world example — Bridging nine orders of magnitude
500 million mev/c2 equals a value comfortably in the human-scale kilogram-force square second/meters range. Physics problems that span this gap are common when comparing the wavelength of light to the path length of an experiment.
5e+8 MeV/c² × 1.817809e-31 = 9.089046e-23 hyl
Real-world example — From sub-micron to human scale
One billion mev/c2 equals one kilogram-force square second/meter — the conversion that drives home the gulf between atomic-scale features and everyday objects in physics curricula.
1e+9 MeV/c² × 1.817809e-31 = 1.817809e-22 hyl
