Real-world measurements rarely match the exact increments of a printed table (e.g., tables often list values in 1°C or 5°F increments).
This is the most traditional format found in engineering handbooks. psychrometric table
The "normal" air temperature measured by a standard thermometer. Real-world measurements rarely match the exact increments of
: [ W = 0.62198 \cdot \fracp_wP - p_w ] (where ( P ) = total atmospheric pressure) psychrometric table
By knowing the air temperature and RH, you can find the in the table.
