Embeddable Fermentation Calculators
Put a live FermentCalc calculator on your own site. Each widget is a small iframe that runs entirely in your visitors' browsers - no accounts, no tracking, no server calls. Copy the code, paste it into your post, done.
Salt needed for a brine of any size and percentage, by water or total weight.
Alcohol by volume from original and final gravity, with attenuation.
Convert refractometer Brix readings to specific gravity.
Add a calculator to your site
Copy the embed code for the widget you want and paste it into your page's HTML where the calculator should appear. Keep the width at 100% for a fluid layout and include the one-line resizer script that comes with the snippet - it keeps the iframe height matched to the content automatically, so you never tune pixels by hand. Two optional URL switches exist for special layouts: add ?chrome=plain to strip the decorative frame, or ?theme=dark to match dark-themed pages.
About the credit link
Every widget carries a small "Powered by getFermentCalc" link at the bottom. It opens in a new tab, so your visitors never leave your page.
