Or this link for exactness if your a profectionanal..... The further you shoot the more this matters. Extreme Spread matters most though I've found? when you get a new scope. Sight it in so it hits exactly where the crosshairs are placed. Then wind up 8clicks shoot , wind up another 8clicks shoot and then measure your results. Wind down 4clicks measure wind down 8clicks and measure. You should get even spaces between shot placings and now you should have custom click measurements to use with that ammunition.... I find this to be a real world solution for the rifle I'm sighting in.... I only worry about the Bloody wind>>>>

Greetings 35whelen,
I got a thorough grounding in UK to metric units in the mid 1970's. I was working as an architectural draughtsman and we were forever converting from feet, inches and fractions of an inch into metres and millimetres. We had a very useful table that helped with this. Affordable pocket calculators were still somewhere in the future. I was still needing to do the conversions from pre 1975 plans right up until I retired in 2015. Worth remembering is that 1 inch is exactly 25.4mm although at one time the UK inch was slightly shorter and the US inch slightly longer. Survey plans were in chains and links which we had to convert into metres, at least this was simpler than feet inches and fractions. Almost all US units were different to the UK ones, just another trap.
