Formula for calculating center to end distance of such elbows is as follows: For 90° Long Radius elbows, center to end dimension given in dimension tables of ASME B16.9 is same as radius of elbow. This is because Tan (90/2) i.e. Tan 45 is 1. Normally custom elbow angles from 45 degree to 90 are cut from 90 degree standard elbow. If that's what you were asking about...
If the circuit is square or rectangular then there will be four 90 degree elbows or bends required.

To calculate the square meters of a duct you must add the total length of the straight duct work plus the loss of length from the elbows. A standard elbows measurement is 15 feet for each elbow with a 4 inch diameter or 20 feet for an elbow with a 6 inch diameter.
Short Radius 90 degree elbows are the same as pipe size.... Long Radius 90's are pipe size times 1.5.... so a 6" (SR) elbow is 6"... a 6" (LR) elbow would be 9"
