peninkulma

Possibly from penin (“dog”) +‎ kuuluma (“to be heard”), the "distance a dog can be heard from". Relation to the Swedish mil is a secondary development.

peninkulma

1. (historical or archaic) an old unit of length, roughly equal to 10 kilometers
   1. exactly 10 kilometers (since 1887)
   2. 10.688 kilometers (1655–1886, equal to one Swedish mil), equivalent to ten virsta
   3. roughly 6 kilometers (before 1655); length varied by region

A Finnish verst (virsta) is slightly longer (1068.8 meters) than the Russian equivalent верста (versta) (1066.8 meters), thus making the length of peninkulma 10.688 kilometers (= 6.64 miles), the same as Swedish mil, before the 1887 adoption of the metric system in Finland.
