1. Celsius, centigrade

The Celsius temperature scale, in which water freezes at 0 degrees and boils at 100 degrees. Japan uses the Celsius scale for all temperature measurements in daily life, weather, and science.

Today's temperature is 30 degrees Celsius.

水(みず)は摂氏(せっし)100度(ど)で沸騰(ふっとう)する。

Usage

Named after the Chinese transliteration of Anders Celsius (摂爾修斯(セルシウス)). In everyday Japanese, temperatures are almost always given in Celsius without explicitly saying 摂氏(せっし) — people simply say 30度(ど) (30 degrees). The word 摂氏(せっし) is used when explicitly distinguishing from Fahrenheit or in scientific contexts.

Common collocations

摂氏(せっし)〜度(ど): ~ degrees Celsius
摂氏(せっし)温度(おんど): Celsius temperature

Similar words
