Is the embedded calculator free to use?

Yes. The widgets are free for any site, including commercial ones. There is no account, no API key, no usage limit and no fee. Keeping the attribution line is requested, not enforced, and removing it does not disable the widget.

Does the widget load tracking scripts or cookies?

No. The framed document contains no JavaScript, sets no cookies, and loads nothing from a third-party domain. Its Content-Security-Policy blocks scripts outright. The form submits to bacwater.ai with a GET request and the entered numbers are not stored.

Can I change the size or remove the attribution line?

Yes to both. Edit the width, height and border in the iframe style, or drop the attribution paragraph entirely. The widget keeps working either way. The attribution is a plain brand link, not a condition of use.

Why is the attribution link outside the iframe?

A link inside an iframe belongs to the framed document rather than to the page doing the framing, so search engines credit it to bacwater.ai instead of treating it as a link from your site. Putting the anchor in the snippet's own markup makes it an ordinary link in your page, which is also why you stay in full control of it.

Does the embedded widget give dosing advice?

No. It divides and converts the numbers a visitor types. It does not select an amount, a liquid, a device or a treatment, and it cannot verify what a vial contains. Every widget links to the full tool page and repeats that the product's own instructions govern.

Will the embedded result match the calculator on bacwater.ai?

Yes. The widget runs the same arithmetic functions as the on-site tools rather than a separate copy, and the test suite asserts the two agree across a table of inputs.

For site owners

Put our calculator on your page

Copy the HTML under any calculator below and paste it into your page. The calculator appears in a frame served from bacwater.ai, so it stays current without you updating anything. It is free for any site, needs no account or API key, and loads no JavaScript, no cookies and nothing from a third-party domain.

Who this is for

Writers, educators, forum operators, veterinary and laboratory reference sites, and anyone explaining reconstitution arithmetic who would rather link to a working calculator than rebuild one. BACwater.ai is a free measurement and concentration utility. It does not sell water or peptides, does not prescribe a treatment and does not select a dose. More about the site.

What the widget does and does not do

It shows arithmetic. Concentration is the vial amount divided by the final liquid volume. A U-100 conversion is a scale relationship: on that scale only, 100 units is 1 mL. 1 mg is 1,000 mcg.
It does not choose anything. No amount, liquid, device, schedule or treatment is selected or suggested, and it cannot confirm what is actually in a vial, whether it is sterile, or how long it keeps.
It works without scripting. The form submits with a GET request and the result is rendered on the server, so it works in readers and with JavaScript disabled.
Nothing is stored. Entered numbers arrive as query parameters, are used to render the response, and are not saved to an account or profile. See the privacy notice.

Prefer to just link?

A plain link is welcome too. The pages people most often reference are the full peptide calculator, the BAC water calculator, the methodology behind every number, and what a calculator cannot tell you.
