Units explained
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.
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.

Step-by-step: convert square inches to outhouses
- Write down the value in square inches (in²).
- Multiply that value by the factor 6.4516e+30.
- The product is the equivalent value in outhouses (outh).
- To reverse, multiply the outhouse value by 1.550003e-31.
Worked examples
Example 1 — Convert 1 in² to outh:
1 × 6.4516e+30 = 6.4516e+30 outh
Example 2 — Convert 100 in² to outh:
100 × 6.4516e+30 = 6.4516e+32 outh
Real-world example — Infrared to visible-spectrum mapping
A 10-square inch thermal infrared wavelength corresponds to a much larger number in outhouses, the unit favoured for ultraviolet and visible-light specifications.
10 in² × 6.4516e+30 = 6.4516e+31 outh
Real-world example — Mid-micron to nanometer
3 square inches equals 3,000 outhouses — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.
3 in² × 6.4516e+30 = 1.93548e+31 outh
Real-world example — From microns to sub-micron features
One square inch equals one thousand outhouses — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.
1 in² × 6.4516e+30 = 6.4516e+30 outh
