Neutron Mass

What is a neutron mass?

The neutron rest mass is about 1.6749E-27 kg, slightly more than the proton.

Origin of the neutron mass

The mass of the neutron, the neutral nucleon.

Where it is used

Nuclear physics and reactor science.

When and where it was developed

Determined after James Chadwick discovered the neutron in 1932.

Seer (Ser) to Neutron Mass conversion formula

Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.

The relationship between seers (ser) and neutron mass:

1 seer = 5.571009e+26 mn
1 mn = 1.795007e-27 seer

To convert seers (ser) to neutron mass, multiply the value in seers (ser) by 5.571009e+26. To reverse, multiply neutron mass by 1.795007e-27.
