Units explained

Scientific / Physics

Shed

What is a shed?

A shed is a humorous physics unit of area equal to exactly 10⁻⁵² m² (10⁻²⁴ barn or 10⁻¹⁸ outhouse).

Origin of the shed

Coined by physicists in extending the 'barn' humor. If the barn is the large building, a 'shed' is much smaller.

Where it is used

Sheds are essentially theoretical and appear in physics jokes rather than serious literature. The actual interaction cross-sections at this scale would require extremely speculative beyond-Standard-Model physics.

When and where it was developed

Physics community humor; theoretical interest only.

Scientific / Physics

Millibarn

What is a millibarn?

A millibarn is a scientific unit of area equal to exactly 10⁻³¹ m² (1/1000 of a barn).

Origin of the millibarn

Derived from the barn using the standard SI milli- prefix.

Where it is used

Millibarns are widely used in particle physics for medium-strength interaction cross-sections. The total proton-proton inelastic cross-section is on the order of 70 mb at LHC energies.

When and where it was developed

Standard derivative of the barn unit.

Shed to Millibarn conversion formula

The relationship between sheds and millibarns:

1 shed = 1e-21 mb
1 mb = 1e+21 shed

To convert sheds to millibarns, multiply the value in sheds by 1e-21. To reverse, multiply millibarns by 1e+21.

How to use this converter

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

Step-by-step: convert sheds to millibarns

  1. Write down the value in sheds (shed).
  2. Multiply that value by the factor 1e-21.
  3. The product is the equivalent value in millibarns (mb).
  4. To reverse, multiply the millibarn value by 1e+21.

Worked examples

Example 1 — Convert 1 shed to mb:
1 × 1e-21 = 1e-21 mb

Example 2 — Convert 100 shed to mb:
100 × 1e-21 = 1e-19 mb

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 sheds can be re-expressed in millibarns for direct comparison with another instrument's calibration data sheet.

800 shed × 1e-21 = 8e-19 mb

Real-world example — Molecular dimensions

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

2 shed × 1e-21 = 2e-21 mb

Frequently asked questions

How many millibarns is 1 shed?
1 shed equals 1e-21 millibarn.
How do I convert sheds to millibarns?
Multiply the value in sheds by 1e-21 to get millibarns.
How do I convert millibarns back to sheds?
Multiply the value in millibarns by 1e+21, or use the Millibarn to Shed converter.
How many millibarns is 100 sheds?
100 sheds equals 1e-19 millibarns, because 100 × 1e-21 = 1e-19.
