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,

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
