# Water

![Enter your water report values as ppm (mg/l)](/files/-LFwu_LgwZDPkgaINYhY)

## 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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.brewfather.app/br/profiles/water.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
