HectopascalToInHg is an alias for MillibarToInHg since 1 hPa = 1 mbar.

func ICAOCountry 

func ICAOCountry(code string) string

ICAOCountry returns the country or territory for a given ICAO code (first two letters)

func ICAORegion 

func ICAORegion(code string) string

ICAORegion returns the region for a given ICAO code (first letter)

func InHgToHectopascal added in v0.3.5 

func InHgToHectopascal(inHg float64) float64

InHgToHectopascal is an alias for InHgToMillibar since 1 mbar = 1 hPa.

func InHgToMillibar added in v0.3.5 

func InHgToMillibar(inHg float64) float64

func InHgToPascal added in v0.3.5 

func InHgToPascal(inHg float64) float64

func IsICAOCode 

func IsICAOCode(code string) bool

IsICAOCode returns true if the code is a valid ICAO airport code prefix (not a full registry check).

func KelvinToCelsius added in v0.3.5 

func KelvinToCelsius(k float64) float64

func KelvinToFahrenheit added in v0.3.5 

func KelvinToFahrenheit(k float64) float64

func KilogramsToPounds added in v0.3.5 

func KilogramsToPounds(kg float64) float64

func KilometersPerHourToKnots 

func KilometersPerHourToKnots(kph float64) float64

func KilometersPerHourToMach 

func KilometersPerHourToMach(kph float64) float64

func KilometersToMeters 

func KilometersToMeters(km float64) float64

func KilometersToNM 

func KilometersToNM(km float64) float64

func KilometersToStatuteMiles added in v0.3.6 

func KilometersToStatuteMiles(km float64) float64

func KnotsToFeetPerSecond added in v0.3.6 

func KnotsToFeetPerSecond(knots float64) float64

func KnotsToKilometersPerHour 

func KnotsToKilometersPerHour(knots float64) float64

func KnotsToMach 

func KnotsToMach(knots float64) float64

func KnotsToMetersPerSecond 

func KnotsToMetersPerSecond(knots float64) float64

func LatLonToOffset added in v0.4.1 

func LatLonToOffset(latRef, lonRef, lat, lon float64) (xEast, zNorth float64)

LatLonToOffset is the inverse of OffsetToLatLon. Given a reference point (latRef, lonRef in decimal degrees) and a target point (lat, lon in decimal degrees), it returns the east (xEast) and north (zNorth) meter offsets of the target from the reference point using the WGS84 ellipsoid.

Parameter order matches OffsetToLatLon for symmetry: 

xEast, zNorth := LatLonToOffset(latRef, lonRef, lat, lon)
lat2, lon2    := OffsetToLatLon(latRef, lonRef, xEast, zNorth)
// lat2 ≈ lat, lon2 ≈ lon (within floating-point precision)

Pole guard: when math.Abs(latRef) >= 90, the eastward direction is undefined; xEast is returned as 0 to avoid a division-by-zero singularity.

func LitersToUSGallons added in v0.3.5 

func LitersToUSGallons(l float64) float64

func MachToKilometersPerHour 

func MachToKilometersPerHour(mach float64) float64

func MachToKnots 

func MachToKnots(mach float64) float64

func MetersPerSecondToFeetPerMinute 

func MetersPerSecondToFeetPerMinute(ms float64) float64

func MetersPerSecondToKnots 

func MetersPerSecondToKnots(ms float64) float64

func NormalizeAngle added in v0.3.6 

func NormalizeAngle(deg float64) float64

NormalizeAngle normalises an angle to (-180, 180]. Useful for signed bearing differences and track deviation calculations.

func NormalizeHeading 

func NormalizeHeading(deg float64) float64

NormalizeHeading returns a heading in [0, 360).

func OffsetToLatLon 

func OffsetToLatLon(latRef, lonRef, xEast, zNorth float64) (lat, lon float64)

OffsetToLatLon calculates the latitude and longitude of a point given a reference point (latRef, lonRef in degrees) and offsets X (east, meters) and Z (north, meters). At the geographic poles (latRef = ±90) eastward offset is undefined; deltaLon is forced to zero to avoid a division-by-zero singularity.

func PascalToInHg(pa float64) float64

func PoundsToKilograms added in v0.3.5
