Units explained
Shed
A shed is a humorous physics unit of area equal to exactly 10⁻⁵² m² (10⁻²⁴ barn or 10⁻¹⁸ outhouse).
Coined by physicists in extending the 'barn' humor. If the barn is the large building, a 'shed' is much smaller.
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.
Physics community humor; theoretical interest only.
Millibarn
A millibarn is a scientific unit of area equal to exactly 10⁻³¹ m² (1/1000 of a barn).
Derived from the barn using the standard SI milli- prefix.
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.
Standard derivative of the barn unit.
Shed to Millibarn conversion formula
The relationship between sheds and millibarns:
To convert sheds to millibarns, multiply the value in sheds by 1e-21. To reverse, multiply millibarns by 1e+21.

Step-by-step: convert sheds to millibarns
- Write down the value in sheds (shed).
- Multiply that value by the factor 1e-21.
- The product is the equivalent value in millibarns (mb).
- 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
