Units explained

Metric / SI

Hectare

What is a 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.

Origin of the hectare

Defined as 100 ares, equal to one square hectometer. The name was introduced in 1795 in France as part of the metric system.

Where it is used

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.

When and where it was developed

Adopted in France in 1795; standardized internationally through the SI system.

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.

Hectare to Outhouse conversion formula

The relationship between hectares and outhouses:

1 ha = 1e+38 outh
1 outh = 1e-38 ha

To convert hectares to outhouses, multiply the value in hectares by 1e+38. To reverse, multiply outhouses by 1e-38.

Step-by-step: convert hectares to outhouses

  1. Write down the value in hectares (ha).
  2. Multiply that value by the factor 1e+38.
  3. The product is the equivalent value in outhouses (outh).
  4. To reverse, multiply the outhouse value by 1e-38.

Worked examples

Example 1 — Convert 1 ha to outh:
1 × 1e+38 = 1e+38 outh

Example 2 — Convert 100 ha to outh:
100 × 1e+38 = 1e+40 outh

Real-world example — Kilometres to wavelengths

One hectare equals one trillion outhouses — a conversion physics teachers use to convey the gulf between everyday geographic and atomic scales.

1 ha × 1e+38 = 1e+38 outh

Real-world example — Geographic to wavelength scale

One hectare equals one trillion outhouses — illustrating the 12-order-of-magnitude span between geographic distance and atomic-feature scales.

1 ha × 1e+38 = 1e+38 outh
