Units explained

Scientific / Physics

Microbarn

What is a microbarn?

A microbarn is a scientific unit of area equal to exactly 10⁻³⁴ m² (10⁻⁶ barn).

Origin of the microbarn

Derived from the barn using the standard SI micro- prefix. Identical in value to the humor unit 'outhouse'.

Where it is used

Microbarns appear in particle physics for moderately rare process cross-sections. They are widely used in heavy-ion physics and electroweak cross-section measurements.

When and where it was developed

Standard derivative of the barn unit.

Scientific / Physics

Outhouse

What is a 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.

Origin of the outhouse

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'.

Where it is used

Outhouses are virtually never used in serious physics literature but exist as a defined humor unit. Microbarn is the preferred professional term.

When and where it was developed

Physics community humor; rarely used in practice.

Microbarn to Outhouse conversion formula

The relationship between microbarns and outhouses:

1 µb = 1 outh
1 outh = 1 µb

To convert microbarns to outhouses, multiply the value in microbarns by 1. To reverse, multiply outhouses by 1.

How to use this converter

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

Step-by-step: convert microbarns to outhouses

  1. Write down the value in microbarns (µb).
  2. Multiply that value by the factor 1.
  3. The product is the equivalent value in outhouses (outh).
  4. 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
