even that, 1.53X is not hard to do in your head, add 50% of n and then add 3% of n.
thus a 30mm becomes 30mm+15mm+0.9mm =45.9mm equiv or 50mm=50mm+25mm+1.5mm=76.5mm equiv. blah blah blah from a practical standpoint 1.5X is going to be close enough I would think in most cases and that's damn elementary my dear watson....
