Muzzle energy is calculated by the formula E=MV2/450400, for English UOM system & E=MV2/2000 for metric where:
M is bullet mass in grains or grams depending on the UOM, 0 < M < 2000.00 grains or 130 grams;*
V is the bullet velocity in ft/sec, 0 < V < 5000.00 fp/sec or 1500 m/sec;*
450400 comes from 7000 ( grains in lb ) by g=32.17 by 2. for English UOM;
2000 comes from 1000 ( grams in kg ) by 2. for metric UOM;
* - Only first two decimal digits are used.
