# Water

![Enter your water report values as ppm (mg/l)](https://559214094-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LEzhWP2LGeXaKgS2qr4%2F-LFwuCLfoX6hfPfYTi9M%2F-LFwu_LgwZDPkgaINYhY%2Fimage.png?alt=media\&token=4924c89e-3429-4735-bd50-22cbc6fc32b1)

## Water Report Conversion

Brewfather uses ppm values for the water profile, so your water report have to be converted to this. Below you will find help converting your values to ppm.

1 **mg/L** = 1 ppm

From **Alkalinity mmol/l** to ppm Bicarbonate HCO3: **multiply by 61**\
From **Alkalinity mg/l CaCO3** to ppm Bicarbonate HCO3: **multiply by 1.22**\
\&#xNAN;*From Alkalinity mmol/l to mg/l CaCO3: multiply by 50*\
\
1000 **ug/L** = 1 ppm\
**ug/L** / 1000 = ppm

### Ion Conversion

Calcium as **CaCO3** ppm \* 0.401 = **Calcium (Ca)** ppm\
Magnesium as **CaCO3** ppm \* 0.243 = **Magnesium (Mg)** ppm\
Sulfate as Sulfur ppm as **SO4-S** \* 3 = **Sulfate (SO4)** ppm\
Bicarbonate as **CaCO3** ppm \* 1.22 = **Bicarbonate (HCO3)** ppm\
\
US Hardness *grains/gallon* \* **6.86** = **Calcium (Ca)** ppm\
°Clark / °e (English) Hardness *grain/imp gallon* \* **5.71** = **Calcium (Ca)** ppm\
German Hardness (°dH, deutsche Härte) \* **7.14** = **Calcium (Ca)** ppm\
Calcium Hardness mEq/L or mval \* **20** = **Calcium (Ca)** ppm\
\
Karbonate Hardness dKH \* **21.8** = **Bicarbonate (HCO3)** ppm\
**Alkalinity mEq/L** or mval \* **61** = **Bicarbonate (HCO3)** ppm\
\
\&#xNAN;*Minor Ions (Currently not in use)*\
\&#xNAN;*Carbonate as **CaCO3 ppm** \* 0.6 = Carbonate (CO3) ppm*\
*Nitrate as Nitrogen **ppm as NO3-N** \* 4.43 = Nitrate (NO3) ppm*

### pH

If the water report does not inlcude the pH you can use 8.0 as pH.
