nubru said:Saw it somewhere cant find it now, how do you get the correct cal/pint Im always showing 43 my waist line belies that ,thanks for any ay input
cal per 12 oz beer = [(6.9 × ABW) + 4.0 × (RE - 0.1)] × FG × 3.55
ABW = 1018. - (277.4 × FG) + RI × [(937.8 × RI) - 1805.]
RE = (0.1808 × IG) + (0.8192 × FG)
