Units explained
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.
Square Inch
A square inch is an imperial unit of area equal to exactly 0.00064516 m², the area of a square with sides of one inch. It is widely used in the United States for small-area measurements.
Derived by squaring the inch. The inch was standardized to exactly 25.4 mm via the 1959 International Yard and Pound Agreement.
Square inches are used extensively in US engineering, manufacturing, real estate (for floor plans), and everyday small-area measurements. Engine displacement is often expressed in cubic inches but cross-sections in square inches.
Inch dates to medieval English usage; modern exact value standardized in 1959.

Step-by-step: convert outhouses to square inches
- Write down the value in outhouses (outh).
- Multiply that value by the factor 1.550003e-31.
- The product is the equivalent value in square inches (in²).
- To reverse, multiply the square inch value by 6.4516e+30.
Worked examples
Example 1 — Convert 1 outh to in²:
1 × 1.550003e-31 = 1.550003e-31 in²
Example 2 — Convert 100 outh to in²:
100 × 1.550003e-31 = 1.550003e-29 in²
Real-world example — Spanning sub-micron to micron scale
Crossing from outhouses to square inches is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 outhouses translates to a much more compact value in square inches that fits the scale of biological cells and process nodes.
1000 outh × 1.550003e-31 = 1.550003e-28 in²
Real-world example — Sub-visible-light wavelength
500 outhouses (the green-yellow visible band) equals 0.5 square inches — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.
500 outh × 1.550003e-31 = 7.750016e-29 in²
