What this is not

The word in the domain name

This site is called Dose to Volume because that is the conversion it performs: an amount you have already written down, turned into the volume of liquid holding it. The word describes the input, not an output. There is no page here that produces a dose, and no field anywhere on the site for a person, a goal, a weight or a condition.

Nothing here states what quantity is appropriate for anyone, and there is no function in it that produces an amount to administer.

That is structural rather than a policy applied on top. Every panel here requires the reader to supply the amount and then converts between representations of what the reader already stated. The calculation engine behind the site holds no compound data, has no model of a person, and contains no function that accepts any of those things and returns a quantity. Arithmetic on a figure somebody else chose is a converter, and a converter cannot recommend.

None of this is medical advice

This is educational arithmetic on figures entered by the reader. It is not medical advice, not a dosing protocol, and not a recommendation that anything be prepared, obtained or administered. Nothing on this site is medical, clinical or pharmaceutical advice, and nothing here is a substitute for it.

A question about anyone’s health belongs with a licensed clinician who can examine the person asking. A decision about anybody's health taken on the strength of a page here is taken against the explicit advice of this notice.

No page states a frequency, a schedule, a route, a duration or a per-kilogram figure, and no page describes how to prepare or administer anything. The amounts in the column headings of the static tables are figures chosen to span the range the division is useful over. They are not suggestions, and the arithmetic of a volume is not an instruction to draw it.

No compound is named anywhere on this site

There is no compound data here of any kind: no names, no molar masses, no potencies, no half-lives. The vials on the static pages are described entirely by two numbers - a mass and a diluent volume - because that is all the conversion needs and all this site knows.

Where a calculation needs a figure from outside, such as the international-units potency, the panel asks for it and says what kind of source it belongs to. A built-in table would be a claim about a preparation this site has never seen.

Compounds of the kind this arithmetic is used on are largely research chemicals that are not approved by the FDA for human use.

No recommendation to get hold of anything

This site does not recommend that any substance be purchased, imported, possessed, prepared or administered, by anyone, for any purpose. No supplier, vendor, pharmacy or compounder is named, ranked, linked or implied anywhere on it, and there is no route from any page here to buying anything.

What is lawful to possess, import, supply or administer differs between jurisdictions and changes over time. Nothing here is an assurance that anything described is lawful where a reader is, and nothing here is legal advice.

Precision in the division, uncertainty in the vial

An exact calculation is not an accurate measurement: what is actually in a syringe depends on the preparation and the device, neither of which this page can see.

The arithmetic is exact: quantities are held as fractions of whole numbers and rounded once, at the point of display. That precision describes the calculation and nothing else. It says nothing about whether a vial contains what its label claims, whether a solid dissolved fully, whether a barrel matches its own printing, or whether a figure was read correctly off it.

Where the inputs do not support a plain answer, the site says so rather than rounding the uncertainty away. A strength derived from a mass and a diluent volume is labelled an upper bound, every volume derived from it is labelled a lower bound, and a reading below two graduations is flagged rather than printed plainly. Those four ways of going wrong have a page each under where it goes wrong.

Who has looked at this

No qualified clinical reviewer is recorded against this site, and no credential is claimed anywhere on it. The arithmetic is covered by an automated test suite and by mutation testing, which introduces deliberate defects into the engine and verifies the tests catch each one. That is evidence about software rather than clinical review, and the two are not substitutes.

No contributor is presented as a physician, pharmacist, chemist or researcher, because none is. No byline, qualification, affiliation or certification appears anywhere on this site, and none is claimed in its structured data.

Error

An arithmetic result that can be shown to be wrong is a defect, and the test suite exists so that such a defect fails the build rather than reaching a reader. A table cell that disagrees with the panel that should have produced it is the same kind of defect, and is why the tables here are generated rather than typed.

The site is offered as it stands, with no warranty of accuracy, completeness or fitness for any purpose. Anyone relying on a figure here for anything that matters should check it independently, which is why every panel shows its arithmetic.
