Calculate

This calculator is setup for 1 gallon of beer at 70°F.

Formula:

var temp = 70;
var volume = 3.78541253426;
var rco2, vco2, gco2;
vco2 = [Desired CO2 volumes];
rco2 = 3.0378 - 5.0062e-2 * temp + 2.6555e-4 * temp * temp;
gco2 = vco2 - rco2;
w = PrimingRate([Priming ingredient]) * v * gco2;

function PrimingRate(u) {
    if (u == "glucose") return 4.02;
    if (u == "sucrose") return 3.82;
    if (u == "honey") return 4.52;
    if (u == "maple") return 7.64;
    if (u == "dme") return 510;
