Tool can be used to measure the size of a force

Nope, it is not true nothing can measure force

The instrument used to measure force is called a dynamometer. A dynamometer is capable of measuring different kinds of force such as mechanical force and muscular force.

That’s really weird? ?

With the name kĺťga (pronounced koh-ga), kĺť means fire. also, ko without the accent mark, means "heart, body and soul." so you could use the name kĺťko. it is not a masculine sounding name in english. you could also use a modified form like kokoro.
