Nanogram

What is a nanogram?

A nanogram (ng) equals 10^-12 kilogram.

Origin of the nanogram

From the SI prefix 'nano-' (from Greek 'nanos', dwarf).

Where it is used

Molecular biology, forensics, and toxicology.

When and where it was developed

The nano- prefix entered the SI in 1960.

Scientific / Atomic

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.

Nanogram to Electron Mass (rest) 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 nanograms and electron mass (rest):

1 ng = 1.097768e+18 me
1 me = 9.10939e-19 ng

To convert nanograms to electron mass (rest), multiply the value in nanograms by 1.097768e+18. To reverse, multiply electron mass (rest) by 9.10939e-19.

How to use this converter

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

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

  1. Write down the value in nanograms (ng).
  2. Multiply that value by the factor 1.097768e+18.
  3. The product is the equivalent value in electron mass (rest) (me).
  4. To reverse, multiply the electron mass (rest) value by 9.10939e-19.

Worked examples

Example 1 — Convert 1 ng to me:
1 × 1.097768e+18 = 1.097768e+18 me

Example 2 — Convert 100 ng to me:
100 × 1.097768e+18 = 1.097768e+20 me

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 nanograms can be re-expressed in electron mass (rest) for direct comparison with another instrument's calibration data sheet.

800 ng × 1.097768e+18 = 8.782147e+20 me

Real-world example — Molecular dimensions

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

2 ng × 1.097768e+18 = 2.195537e+18 me
