As we know, the mass of well known particles are below.

$m_{n}\approx0.0000000000000000000000000016749286[kg]$

$m_{p}\approx0.0000000000000000000000000016726231[kg]$

$m_{e}\approx0.00000000000000000000000000000091093897[kg]$

I roughly know the way how to measure the electron's mass, but I don't know rest two of them.

Any answers will be apreciated, Thank you.
