Using BiologyCalc

A free educational resource

You are welcome to use our calculators for learning and everyday planning. They provide calculations based on the inputs and assumptions shown on each page. Biological systems vary, and estimates may not match an individual animal, plant, experiment, or site.

Use judgment with your results

Check units and input values before relying on a result. The site does not provide a veterinary diagnosis, a treatment plan, or a guarantee of any outcome. Seek qualified advice when your question needs professional assessment.

We aim to make accurate, useful tools, but cannot promise that every result is appropriate for every purpose or that the service will always be available. The formulas and worked examples help you check how an answer was obtained.

Respect the website

Do not misuse the service or interfere with other visitors’ access. Links to reference websites are provided for further reading; including a link does not imply that those organizations endorse BiologyCalc.
