たいしぼうけい

noun

body fat scale; body fat meter

1. body fat scale; body fat meter; body composition monitor

A household device that measures body fat percentage, usually a bathroom scale that also estimates body composition by passing a weak electrical current through the body. Many modern models also report muscle mass, visceral fat, basal metabolic rate, and similar metrics.

Composed of 体脂肪(たいしぼう) (body fat) and the suffix 計(けい) (measuring device). The word refers specifically to the consumer device, not to professional body-composition equipment used in hospitals or gyms (which is more likely called 体組成計(たいそせいけい)).

Usage

In Japan, most home bathroom scales sold today are 体脂肪計(たいしぼうけい) rather than plain weight scales — the word is essentially interchangeable with "bathroom scale" in modern usage.
