Those aren't the same thing. You're asking to convert horsepower to meters.

You can turn Euler angles into a quaternion, or a rotation matrix. Then 
you can rotate a unit vector by that quaternion or matrix to get another 
vector. However, you have to know what unit vector to start with.

Ask yourself this question: what vector would you want to get out if all 
the Euler angles were 0? That's your identity vector. Now, convert the 
euler angles to rotation matrix, and translate the identity vector by 
that matrix; out comes the vector you want.
