This formula uses 4 Variables

Variables Used

Group Refractive Index - Group Refractive Index is the he ratio of the vacuum velocity of light to the group velocity in a medium.
Barometric Pressure - Barometric Pressure is the pressure on earth that is caused by the weight of the air above us. It is sometimes the atmospheric pressure. It should be entered in millibar.
Temperature in Celsius - Temperature in Celsius is the degree of coolness or hotness of any substance. It should be entered in degree celsius.
Partial Pressure of Water Vapour - (Measured in Millibar) - Partial pressure of water vapour is the vapour pressure in any gas mixture in equilibrium with solid or liquid water.

STEP 1: Convert Input(s) to Base Unit

Barometric Pressure: 6921.213 --> No Conversion Required
Temperature in Celsius: 98 --> No Conversion Required
Partial Pressure of Water Vapour: 1006 Millibar --> 1006 Millibar No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n = 1+(0.000077624*P_b/(273.15+t))-(((12.924/(273.15+t))+(371900/(273.15+t)^2))*10^-6*e) --> 1+(0.000077624*6921.213/(273.15+98))-(((12.924/(273.15+98))+(371900/(273.15+98)^2))*10^-6*1006)

Evaluating ... ...

n = 0.998696531922686

STEP 3: Convert Result to Output's Unit

0.998696531922686 --> No Conversion Required

FINAL ANSWER

0.998696531922686 ≈ 0.998697 <-- Group Refractive Index
