## Strike Temperature Calculator

Credit To: http://www.rackers.org/calcs.shtml

Calculate the temperature your strike water needs to be in order
to hit the desired mash-in temperature. Assumes your brewing for 5 gallons,
with basic mash-tun cooler.

Mash Thickness (quarts of water/lbs of grain or liters of Water/Kgs of grain)

Desired Strike Temperature (deg F or C)

Temperature of Grain (deg F or C)

Units of Measurement: American Metric

Or.... if you want to calculate it yourself:

```Ts = Td + (.192 * (Td-Tg)/Gr)) + 3

Where:
* Ts = Final Strike Temp
* Td = Desired Strike Temp
* Tg = Current Grain Temp
* Gr = Grain Ratio

Notes: .192 is the "water equivalent" or volume of water whose heat
capacity is equivalent to that of a given mass/weight of grain
based on specific heat of grain being 0.4

3 is the temperature added to account for heat loss during transfer
or put more succintly; the "Fudge Factor" to account for thermal mass lost
(3 deg for F or 1.7 deg for C)
