About these units
The btu per pound °f (BTU/(lb·°F)) is an imperial unit of specific heat capacity, equal to 4,186.8 joules per kilogram kelvin.
The kilojoule per kilogram kelvin (kJ/(kg·K)) is a metric unit of specific heat capacity, equal to 1,000 joules per kilogram kelvin.
Going the other way, 1 kilojoule per kilogram kelvin = 0.2388459 btu per pound °f. Specific heat capacity is the energy needed to warm one unit of mass by one degree. Water sits at about 4.186 kJ/(kg·K), which is exactly why the calorie and the BTU were defined the way they were: 1 cal/(g·°C) equals 1 BTU/(lb·°F).
