传热系数的换算
1 kcal/m2. Time (kcal/m2.h) =1.16279 w/m2 (w/m2)
1 kcal/(m.. ℃) [1 kcal/(m.h. ℃)) = 1.16279 w/(m. Kelvin) w/(m2. K)
1. Btu/(FT2.h.)) =5.67826 watts /(m. Kelvin)
1.2m. Hour.℃/kcal (M2.h.℃/kcal) =0.86000 m. 2.Kelvin/watt (M2.k /W)
1 kcal (m.. ℃) (kcal/(m.h. ℃)) = 1.16279 W/(m. Kelvin) W/(m.K)
1 btu/(feet.. ℉) But/(ft. H. ℉) = 1.7303 W/(m. Kelvin) W/(m.K)
比热转换
1 kcal/kg. ℃) kcal/(kg) ℃) = 1 / British thermal unit (pounds. ℉) Btu/lb. ℉) (= 4186.8 joules/(kg. Kelvin) (J/kg. (K))
