The table below shows ranges and default units of measure for each of the five properties involved in steam function calculations.

The default units of measure are SI units. For information about using steam functions with other units of measure, see Understand unit of measure conversion for steam functions.

Pressure affects the state of steam. Several things to keep in mind for functions with pressure as an input are described in Learn about steam functions that have pressure as an input.
