Template:Convert/horse year

The converter Template:Convert/horse_year changes a time span, such as 3 horse years, into the equivalent people years. Although horse years could be averaged as roughly 3 people years, the conversion is based on the typical maturation rate of horses: first year as 12 years, 2nd as 7 more years, 3rd-5th as 4 years each, then above 5 as 2.5 years each.

Examples
The following show the variation in the horse maturation rate:
 * 1 horse year  → 1 horse year
 * 2 horse year  → 2 horse year
 * 3 horse year  → 3 horse year
 * 4 horse year  → 4 horse year
 * 5 horse year  → 5 horse year
 * 6 horse year  → 6 horse year
 * 0.7 horse year  → 0.7 horse year
 * 4.4 horse year  → 4.4 horse year
