Runway Crosswinds

Runway (i.e. 220)	Wind Direction (i.e. 270)	Wind Speed Knots

The Crosswind is	Knots

Fahrenheit to Celsius
This conversion of temperature is made using the formula (Fahrenheit temperature * 9/5) + 32)

Enter �F

Calculated Temperature = �C

Wind Chill
Wind chill cannot be accurately calculated for outside air temperatures (OAT) greater that 50 �F (10 �C) and wind speeds less than 4 MPH (3.5 Knots).

Enter Temperature (OAT) �F �C

Enter Wind MPH Knots

Calculated Wind Chill = �F or �C

Heat Index
Determine the heat index from the outside air temperature (OAT) and Relative Humidity.

Enter Temperature (OAT) �F �C

Enter % Relative Humidity

Calculated Heat Index = �F or �C

Dewpoint
Calculate the Dewpoint from the outside air temperature (OAT) and Relative Humidity

Enter Temperature (OAT) �F �C

Enter % Relative Humidity

Calculated Dewpoint = �F �C

Relative Humidity
Calculate the Relative Humidity from the outside air temperature (OAT) and Dewpoint

Enter Temperature (OAT) �F �C

Enter Dewpoint �F �C

Calculated Relative Humidity = %

Pressure Conversion
Convert Millibars to Inches of Mercury and Inches of Mercury to Millibars

Enter Millibars Inches Mercury

Converted Barometric Pressure =

Miles Per Hour To Knots
This conversion of speed (or distance) is made using the formula (Knots (or nautical miles) = MPH (or miles) * 0.86897624)

Enter MPH or Statute Miles

Calculated Knots Or Nautical Miles =

Knots to Miles Per Hour
This conversion of speed (or distance) is made using the formula (MPH (or statute miles) = Knots (or nautical miles) * 1.15077945)

Enter Knots or Nautical Miles

Calculated MPH or Statute Miles =

True Airspeed (TAS or KTAS)
Result can be either Knots or MPH based on consistent entry of the same designation. The formula is (IAS) + (.02 x MSL / 1000).
