Femtogram

What is a femtogram?

A femtogram (fg) equals 10^-18 kilogram.

Origin of the femtogram

From the SI prefix 'femto-' (from Danish/Norwegian 'femten', fifteen).

Where it is used

Nanotechnology and high-sensitivity mass spectrometry.

When and where it was developed

The femto- prefix was adopted by the CGPM in 1975.

Scientific / Atomic

Muon Mass

What is a muon mass?

The muon rest mass is about 1.884E-28 kg.

Origin of the muon mass

The mass of the muon, a heavy cousin of the electron.

Where it is used

Particle and high-energy physics.

When and where it was developed

Determined after the muon was discovered in cosmic rays in 1936.

Femtogram to Muon 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 femtograms and muon mass:

1 fg = 5.309172e+9 mµ
1 mµ = 1.883533e-10 fg

To convert femtograms to muon mass, multiply the value in femtograms by 5.309172e+9. To reverse, multiply muon mass by 1.883533e-10.

How to use this converter

Type a value into the calculator. The result in muon mass updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Muon Mass to Femtogram converter for the reverse direction.

Step-by-step: convert femtograms to muon mass

  1. Write down the value in femtograms (fg).
  2. Multiply that value by the factor 5.309172e+9.
  3. The product is the equivalent value in muon mass (mµ).
  4. To reverse, multiply the muon mass value by 1.883533e-10.

Worked examples

Example 1 — Convert 1 fg to mµ:
1 × 5.309172e+9 = 5.309172e+9 mµ

Example 2 — Convert 100 fg to mµ:
100 × 5.309172e+9 = 5.309172e+11 mµ

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 femtograms can be re-expressed in muon mass for direct comparison with another instrument's calibration data sheet.

800 fg × 5.309172e+9 = 4.247338e+12 mµ

Real-world example — Molecular dimensions

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

2 fg × 5.309172e+9 = 1.061834e+10 mµ
