[QUOTE="Sami, post: 612185, member: 40444"] Brent, For those of us who use metric as a base, easy measurements are either 1m (upper torso of a man, height of the average whitetail etc) or 30cm which is almost equal to 12" and approximate the size of a human head for example. If you can find targets that size on your game, mils becomes a VERY easy calculation. For you example, your 19" estimate is very close to 50cm, an easy mil calculation again. 0.5m * 1000 / 2 = 250m Even if you went with straight inch to m conversion, calculating distance is still easy: 0.4826m * 1000 / 2 = 241.3m ( = 263.888 yd) There is always going to be error margin on both methods. First is the estimation of target size but with inches and yards you also have a error margin coming from the conversion. 19/36 = 0.53 is a rounded number from 0.52777...... Then add the error margin from the estimation of the mils on the reticle...so all I can say is practice, whatever system you use! :D [/QUOTE]
