It wont really work like that im affraid.
Each persons swing is different, power is not always equal.
For arguements sake, 180 yards away from the green, I may hit a 7 iron and but my playing partner takes a 4 iron - we would both end up the same distance but as I hit the ball further than him we would each use different clubs.
The only way to yard your clubs is to go down to a driving range where they have markers set at certain distances. Hit 50 balls using a 5 iron and see where they fall. Then hit 50 balls using a 8 iron etc etc.
