For example, using UK government Livestock Units (LUs) from the 2003 scheme [1] a particular 10 ha (25-acre) pasture field might be able to support 15 adult cattle or 25 horses or 100 sheep: in that scheme each of these would be regarded as being 15 LUs, or 1.5 LUs per hectare (about 0.6 LUs per acre).
For example, each of the following converts 1.2 km 2 to acres, square yards, and hectares. {{convert|1.2|km2|acre sqyd ha}} → 1.2 square kilometres (300 acres; ...
