UKismetMathLibrary::Vector_ToRadians
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Converts each component of a vector from degrees to radians, returning (X*PI/180, Y*PI/180, Z*PI/180). Useful when a vector is used to store Euler angles and you need radians for trigonometric functions.
Caveats & Gotchas
- • This is a pure component-wise multiply by PI/180. It has no special meaning for direction vectors — only use it when the vector actually stores degree values.
- • UE functions like FRotator and most rotation math use degrees internally. Only convert to radians when calling sin/cos/tan directly or passing to a radians-expecting API.
- • Pair with Vector_ToDegrees for the reverse conversion. Note that Vector_UnwindEuler operates in degrees, so unwind before converting.

FVector Example
Convert a degree Euler vector before passing to FQuat C++
FVector EulerDegrees(45.f, 0.f, 90.f);
FVector EulerRadians = UKismetMathLibrary::Vector_ToRadians(EulerDegrees);
// Each component is now in radians for use with FMath::Sin/Cos etc.Version History
