Here are some other ways to express the mass of a proton:

* 1.6726219 × 10^-27 kg (kilograms)

* 1.007276 u (unified atomic mass unit)

* 938.272 MeV/c² (megaelectronvolts per speed of light squared, which is the energy equivalent mass)

It's important to note that these are approximate values, as the mass of a proton can vary slightly depending on its environment and interactions.
