2、。人的體溫測(cè)量就是用華氏溫度的。溫測(cè)量就是用華氏溫度的。1740年瑞典人攝氏年瑞典人攝氏(Celsius)提出在標(biāo)準(zhǔn)大氣壓下，把冰水混合物的溫度提出在標(biāo)準(zhǔn)大氣壓下，把冰水混合物的溫度定為定為0攝氏度，水的沸點(diǎn)規(guī)定為攝氏度，水的沸點(diǎn)規(guī)定為100度。根據(jù)水這兩個(gè)固定溫度點(diǎn)來(lái)對(duì)玻度。根據(jù)水這兩個(gè)固定溫度點(diǎn)來(lái)對(duì)玻璃水銀溫度計(jì)進(jìn)行分度。兩點(diǎn)間作璃水銀溫度計(jì)進(jìn)行分度。兩點(diǎn)間作100等分，每一份稱(chēng)為等分，每一份稱(chēng)為1攝氏度。記作攝氏度。記作1。華氏和攝氏的換算華氏和攝氏的換算: 華氏度華氏度 = 32 + 攝氏度攝氏度 1.8 攝氏度攝氏度 = (華氏度華氏度 - 32) 1.8數(shù)據(jù)數(shù)據(jù): 0C=32F 1
