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.
Hectare
A hectare is a metric unit of area equal to 10,000 square meters, or one square hectometer. It is the most widely used metric unit for land measurement worldwide.
Defined as 100 ares, equal to one square hectometer. The name was introduced in 1795 in France as part of the metric system.
Hectares are the standard unit for agricultural land measurement worldwide except in the US (which uses acres). 1 hectare equals 2.47105 acres. In India, hectares are used in modern agricultural census and land records alongside traditional regional units.
Adopted in France in 1795; standardized internationally through the SI system.

Step-by-step: convert outhouses to hectares
- Write down the value in outhouses (outh).
- Multiply that value by the factor 1e-38.
- The product is the equivalent value in hectares (ha).
- To reverse, multiply the hectare value by 1e+38.
Worked examples
Example 1 — Convert 1 outh to ha:
1 × 1e-38 = 1e-38 ha
Example 2 — Convert 100 outh to ha:
100 × 1e-38 = 1e-36 ha
Real-world example — Twelve orders of magnitude
A trillion outhouses maps to a single, recognizable distance in hectares. This kind of conversion arises in cosmology and electromagnetic-spectrum exercises where atomic and astronomical scales sit side by side.
1e+12 outh × 1e-38 = 1e-26 ha
Real-world example — Wavelength to road distance
A trillion outhouses equals one hectare — the kind of conversion that appears in physics problems spanning the electromagnetic spectrum across many orders of magnitude.
1e+12 outh × 1e-38 = 1e-26 ha
