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

Barn

What is a barn?

A barn is a scientific unit of area equal to exactly 10⁻²⁸ m² (100 fm²). It is used in nuclear and particle physics to express interaction cross-sections.

Origin of the barn

Named in 1942 at Purdue University by physicists working on the Manhattan Project. The name comes from the phrase 'big as a barn' — uranium nuclei have cross-sections this large, which physicists initially considered surprisingly large for nuclear targets.

Where it is used

Barns and their submultiples (millibarn, microbarn, nanobarn, picobarn, femtobarn) are the standard units for cross-section measurements in nuclear physics, high-energy physics, and accelerator experiments. The Higgs boson production cross-section at the LHC is in the picobarn range.

When and where it was developed

Named in 1942 during the Manhattan Project; adopted internationally in particle physics.

Shed to Barn conversion formula

The relationship between sheds and barns:

1 shed = 1e-24 b
1 b = 1e+24 shed

To convert sheds to barns, multiply the value in sheds by 1e-24. To reverse, multiply barns by 1e+24.

How to use this converter

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

Step-by-step: convert sheds to barns

  1. Write down the value in sheds (shed).
  2. Multiply that value by the factor 1e-24.
  3. The product is the equivalent value in barns (b).
  4. To reverse, multiply the barn value by 1e+24.

Worked examples

Example 1 — Convert 1 shed to b:
1 × 1e-24 = 1e-24 b

Example 2 — Convert 100 shed to b:
100 × 1e-24 = 1e-22 b

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 barns for direct comparison with another instrument's calibration data sheet.

800 shed × 1e-24 = 8e-22 b

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-24 = 2e-24 b

Frequently asked questions

How many barns is 1 shed?
1 shed equals 1e-24 barn.
How do I convert sheds to barns?
Multiply the value in sheds by 1e-24 to get barns.
How do I convert barns back to sheds?
Multiply the value in barns by 1e+24, or use the Barn to Shed converter.
How many barns is 100 sheds?
100 sheds equals 1e-22 barns, because 100 × 1e-24 = 1e-22.
