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.
Square Millimeter
A square millimeter is a metric unit of area equal to 10⁻⁶ m² (1 mm × 1 mm). It is widely used in engineering, electronics, and small-scale technical work.
Derived by squaring the millimeter, defined as 1/1000 of a meter. The milli- prefix comes from the Latin 'mille' (thousand).
Square millimeters express PCB trace cross-sections, the area of small mechanical features in CAD drawings, biological sample sizes, and material thicknesses.
Millimeter has been part of the metric system since 1795.
Shed to Square Millimeter conversion formula
The relationship between sheds and square millimeters:
To convert sheds to square millimeters, multiply the value in sheds by 1e-46. To reverse, multiply square millimeters by 1e+46.

Step-by-step: convert sheds to square millimeters
- Write down the value in sheds (shed).
- Multiply that value by the factor 1e-46.
- The product is the equivalent value in square millimeters (mm²).
- To reverse, multiply the square millimeter value by 1e+46.
Worked examples
Example 1 — Convert 1 shed to mm²:
1 × 1e-46 = 1e-46 mm²
Example 2 — Convert 100 shed to mm²:
100 × 1e-46 = 1e-44 mm²
Real-world example — Sub-visible-light wavelength
500 sheds (the green-yellow visible band) equals 0.5 square millimeters — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 shed × 1e-46 = 5e-44 mm²
Real-world example — Spanning sub-micron to micron scale
Crossing from sheds to square millimeters is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 sheds translates to a much more compact value in square millimeters that fits the scale of biological cells and process nodes.
1000 shed × 1e-46 = 1e-43 mm²
