Water Calculator: Allow user to select the preferred unit

[lucianthorr]

In the Acid Additions section of the water calculator, the "Specify acid by target mash pH" option is awesome for generating the perfect amount but it would be great if it allowed the user to change the Unit. I don't have a way to measure mL of lactic acid so it takes manual conversion and then disabling the option in order to record the correct amount in a unit of measurement that I can work with

My local pharmacy sold me a 10 ml syringe body (no needle), it does what I need.

That said, this screen shot shows that the units (ml here) can be selected. Just tap or click the blue ‘ml’ text for a pop up window.

Or am I missing something?

@Yooper FYI.

Hi, thanks! Yeah, I do feel like maybe I just need something for ml measurements.

You’re right that you can change units but when the amount is auto-populated, it’s locked to ml. You can change it but it will change back.
I’m guessing because the conversion from volume to weight is nontrivial but it’d sure be cool if it worked that way.

Huh. Never tried it. But volume to weight is trivial if you know the (liquid’s) density. And one could safely assume it is 1.0 (1gram = 1ml) since the error would be small enough to ignore, particularly at our scale.

Yeah, it's totally a nitpick request but it's gotten me a few times over the years when brewing and all of a sudden a recipe changes to a kind of measurement that I don't have the tools for... and then I have to trust myself to do the math correctly

A possible work around for you that could mitigate this would be to use acidulated malt.
I have been doing this for years, my reason for switching to this is that I always seemed to forget to add the lactic acid to the mash.
