【 体温計・taionkei 】medical thermometer

体温 (たいおん taion) = body temperature

計る (はかる hakaru) = measure

We use the metric system in Japan so body temperatures are measured in Celsius.

平熱 (へいねつ heinetsu) = normal body temperature
36.5–37.5 °C (equal to 97.7–99.5 °F)

発熱 (はつねつ hatsunetsu) = a fever
any temperature above an individual’s normal body temperature

微熱 (びねつ binetsu) = slightly feverish
37-38 °C

高熱 (こうねつ konetsu) = a high fever
body temperature above 38.0°C

On the other end of the spectrum,

低体温症 (ていたいおんしょう teitaionshō) = hypothermia
body temperature below 35.0°C

Now, how would you read “36.8 °C” in Japanese?

When reading a medical thermometer, you would read whole numbers with 度 (ど do), as in degree, and decimals with 分 (ぶ bu).

So 36.8 °C would be 36度8分 (さんじゅうろくどはちぶ sanjyūrokudohachibu).

When measuring other degrees (like an angle), it is more common to say てん (ten) for the decimal and say 36.8度 (さんじゅうろくてんはちど sanjyūrokudohachibu).

Both °C and °F are 度 (do), but you would usually add 華氏 (かし kashi; Farenheit) as a prefix to avoid confusion.

50°F = 華氏50度 (kashi gojyūdo)

The flu is インフルエンザ (infuruenza) in Japanese, インフル for short. 

(I’m) feverish

(netsu ga arukamo)
I might have a fever.

(kaze wo hiitakamo)
I might have caught a cold.

(infuruenza janaito iindakedo)
I hope it’s not the flu.
