Stone (US)

What is a stone (us)?

A less common US definition of the stone, about 5.67 kilograms.

Origin of the stone (us)

A variant stone weight used in some historical US trade.

Where it is used

Rare; appears mainly in historical or specialized contexts.

When and where it was developed

Derived from older English stone weights that varied by commodity.

Scientific / Atomic

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.

Stone (US) 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 stones (us) and neutron mass:

1 st = 3.385162e+27 mn
1 mn = 2.954068e-28 st

To convert stones (us) to neutron mass, multiply the value in stones (us) by 3.385162e+27. To reverse, multiply neutron mass by 2.954068e-28.
