Btu（热力学）
Btu（热化学）变体与热化学卡路里一致，定义为在一大气压下将一磅水的温度提高一华氏度所需的能量，大约相当于1,054.350焦耳。
卡路里（15°C，NBS 1939）
15°C NBS 1939卡路里是指在标准大气压下，将一克水的温度从14.5°C升高到15.5°C所需的能量。这一特定定义是由国家标准局（NBS）在1939年制定的。

Btu（热力学） 到 卡路里（15°C，NBS 1939） 转换公式
卡路里（15°C，NBS 1939） = Btu（热力学） * 251.88755139
Btu（热力学） 到 卡路里（15°C，NBS 1939） 计算
卡路里（15°C，NBS 1939） = Btu（热力学） * 251.88755139
卡路里（15°C，NBS 1939） = 1 * 251.88755138642
卡路里（15°C，NBS 1939） = 251.88755
