Electron's weight
WebMar 23, 2024 · An electron’s weight is 89.27 x 10-31. Weight depends on the gravity on an object, so it can vary. Scientists use the 'rest mass' – the electron mass that isn't moving. While the electron’s ‘weight’ is 89.27 x 10-31, the mass is this value divided by the gravity force, resulting in 9.109 x 10-31. Though we are more accustomed to using ...
