E6B - Temperature Calculations

Temperature calculations in both Fahrenheit and Celsius, and Dewpoint determination.

Fahrenheit to Celsius

This conversion is made using the formula Fahrenheit = ((9/5)*Celsius)+32
Enter: °F
Calculated Temperature = °C

Celsius to Fahrenheit

This conversion is made using the formula Celsius = (5/9)*(Fahrenheit-32)
Enter: °C
Calculated Temperature = °F

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

Determines 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

Calculates the Dewpoint from the outside air temperature (OAT) and Relative Humidity.
Enter: Temperature (OAT) °F °C
Enter: % Relative Humidity
Calculated Dewpoint = °F or °C

Relative Humidity

Calculates the Relative Humidity from the outside air temperature (OAT) and Dewpoint.
Enter: Temperature (OAT) °F °C
Enter: Dewpoint°F °C
Calculated Relative Humidity = %

E6B - Speed Calculations

Calculates True Airspeed and does conversions from MPH to Knots or Knots to MPH.

True Airspeed (TAS or KTAS)

Units can be either Knots or MPH based on consistent entry of the same designation. The formula is (IAS) + (.02 x MSL / 1000).
Enter: Indicated Air Speed
Enter: MSL Altitude
Calculated True Airspeed =

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 =
