    Radians to degrees and so forth is quite easy, as long as you remember a system in your head.

    Remember, 1 radian is approximately 57 degrees, so if you are unsure of a calculation, just see if it makes sense in your head.

    So, 1 radian = pi/180,

    2.345 rads to degrees.

    AND

    158.8 degrees to rads

    So, 2.345 * 57 will be around 130, but to get it exactly,
    2.345* 180/pi = 422.1/pi (literally the 3.14 button on your calculator) gets you 134.358

    As for 158.8 degrees to rads, just go 158.8/57 is around 2.77, or exactly

    158.8 * pi / 180 = 2.757
