Square Hectometer [hm²]
A square hectometer (hm²) is a unit of area equal to a square with sides 1 hectometer (100 meters) long.
1 hm² = 10,000 m² = 1 hectare (ha).
It is used to measure large areas like fields or forests, similar to hectares.
Square Mile (US Survey)
The square mile (US survey) is a unit of area used in the United States for land measurement based on the US survey foot. It represents a square with sides 1 mile long, where a mile is defined using the survey foot rather than the international foot.
1 US survey mile = 5,280 US survey feet
1 square mile (US survey) ≈ 2.589998 km² (slightly different from the international square mile of 2.59 km²)
This unit is mostly used in land surveying and mapping within the US.
