When I watched the Winter Olympics last month was befuddled trying to mentally translate the names for the tricks into what the skier or boarder was doing. The twists and spins aren’t measured in fractions of a full rotation, like diving, but rather in degrees. I can understand if fractions are too complicated for some folks, but this mentally dividing by 360 stuff is too complicated for me, and, I suspect, for others.

So, in honor of Pi Day (that’s today), I have a suggestion: measure the number of revolutions in radians. Here’s a conversion guide:

- 360: two pi
- 540: three pi
- 720: four pi
- 900: five pi
- 1080: six pi
- 1260: seven pi
- 1440: eight pi

Note that in all cases, the new terms are faster to say. And, if you need to get the number of rotations, it’s a lot easier to divide by 2 than 360.

Freestylers, you’re welcome.

degrees per “full circle spin”: “#” and “#+”

360: 1

540: 1+

720: 2

900: 2+

1080: 3

1260: 3+

1440: 4

# = 360

where: “+” = +180

no division necessary

Sure, but where’s the math geek fun in that?
