Ammonia - Thermal Conductivity vs. Temperature and Pressure

Calculator for thermal conductivity of ammonia at given temperatures and pressures. Thermal conductivity is a material property describing the ability to conduct heat. Output conductivity is provided in multiple units: mW/(m K), Btu(IT)/(h ft °F), and kcal(IT)/(h m K).
