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.

Force / Engineering

Slug

What is a slug?

The slug is the mass that accelerates at 1 ft/s^2 under a force of one pound-force, about 14.59 kg.

Origin of the slug

Coined in the early 20th century for the British gravitational (engineering) system.

Where it is used

US and British engineering dynamics.

When and where it was developed

Introduced in the British gravitational system of units.

Electron Mass (rest) to Slug 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 slugs:

1 me = 6.241915e-32 slug
1 slug = 1.602073e+31 me

To convert electron mass (rest) to slugs, multiply the value in electron mass (rest) by 6.241915e-32. To reverse, multiply slugs by 1.602073e+31.

How to use this converter

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

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

  1. Write down the value in electron mass (rest) (me).
  2. Multiply that value by the factor 6.241915e-32.
  3. The product is the equivalent value in slugs (slug).
  4. To reverse, multiply the slug value by 1.602073e+31.

Worked examples

Example 1 — Convert 1 me to slug:
1 × 6.241915e-32 = 6.241915e-32 slug

Example 2 — Convert 100 me to slug:
100 × 6.241915e-32 = 6.241915e-30 slug

Real-world example — Molecular dimensions

The diameter of small molecular structures (around 2 electron mass (rest)) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.

2 me × 6.241915e-32 = 1.248383e-31 slug

Real-world example — Wavelengths across the spectrum

Optical and atomic-scale phenomena are routinely cross-converted between sub-micron units. A photon of wavelength 800 electron mass (rest) can be re-expressed in slugs for direct comparison with another instrument's calibration data sheet.

800 me × 6.241915e-32 = 4.993532e-29 slug
