Units explained
Microbarn
A microbarn is a scientific unit of area equal to exactly 10⁻³⁴ m² (10⁻⁶ barn).
Derived from the barn using the standard SI micro- prefix. Identical in value to the humor unit 'outhouse'.
Microbarns appear in particle physics for moderately rare process cross-sections. They are widely used in heavy-ion physics and electroweak cross-section measurements.
Standard derivative of the barn unit.
Outhouse
An outhouse is a humorous physics unit of area equal to exactly 10⁻³⁴ m² (10⁻⁶ barn), identical in value to the microbarn.
Coined by physicists as a humorous extension of the 'barn' nomenclature: if the barn is a large physics target, then by analogy something millionfold smaller is an 'outhouse'.
Outhouses are virtually never used in serious physics literature but exist as a defined humor unit. Microbarn is the preferred professional term.
Physics community humor; rarely used in practice.
Microbarn to Outhouse conversion formula
The relationship between microbarns and outhouses:
To convert microbarns to outhouses, multiply the value in microbarns by 1. To reverse, multiply outhouses by 1.

Step-by-step: convert microbarns to outhouses
- Write down the value in microbarns (µb).
- Multiply that value by the factor 1.
- The product is the equivalent value in outhouses (outh).
- To reverse, multiply the outhouse value by 1.
Worked examples
Example 1 — Convert 1 µb to outh:
1 × 1 = 1 outh
Example 2 — Convert 100 µb to outh:
100 × 1 = 100 outh
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 microbarns can be re-expressed in outhouses for direct comparison with another instrument's calibration data sheet.
800 µb × 1 = 800 outh
Real-world example — Molecular dimensions
The diameter of small molecular structures (around 2 microbarns) is often converted into related sub-micron units when comparing measurements across different microscopy techniques or imaging modalities.
2 µb × 1 = 2 outh
