Electron Mass (rest)

What is a electron mass (rest)?

The electron rest mass is about 9.109E-31 kg.

Origin of the electron mass (rest)

The mass of the electron, the lightest charged elementary particle.

Where it is used

Atomic and particle physics.

When and where it was developed

Quantified after J. J. Thomson identified the electron in 1897.

Avoirdupois

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.

Electron Mass (rest) to Stone (US) 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 electron mass (rest) and stones (us):

1 me = 1.606621e-31 st
1 st = 6.224242e+30 me

To convert electron mass (rest) to stones (us), multiply the value in electron mass (rest) by 1.606621e-31. To reverse, multiply stones (us) by 6.224242e+30.

How to use this converter

Type a value into the calculator. The result in stones (us) updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Stone (US) to Electron Mass (rest) converter for the reverse direction.

Step-by-step: convert electron mass (rest) to stones (us)

  1. Write down the value in electron mass (rest) (me).
  2. Multiply that value by the factor 1.606621e-31.
  3. The product is the equivalent value in stones (us) (st).
  4. To reverse, multiply the stone (us) value by 6.224242e+30.

Worked examples

Example 1 — Convert 1 me to st:
1 × 1.606621e-31 = 1.606621e-31 st

Example 2 — Convert 100 me to st:
100 × 1.606621e-31 = 1.606621e-29 st

Real-world example — From sub-micron to human scale

One billion electron mass (rest) equals one stone (us) — the conversion that drives home the gulf between atomic-scale features and everyday objects in physics curricula.

1e+9 me × 1.606621e-31 = 1.606621e-22 st

Real-world example — Bridging nine orders of magnitude

500 million electron mass (rest) equals a value comfortably in the human-scale stones (us) range. Physics problems that span this gap are common when comparing the wavelength of light to the path length of an experiment.

5e+8 me × 1.606621e-31 = 8.033107e-23 st
