Trust & transparency
Terms of service
Please read these terms carefully before using Biology Calculator. By accessing our tools, reference data, and guides, you agree to be bound by the terms, disclaimers, and liability limits set forth below.
1. Acceptance of terms
Biology Calculator ("biologycalculator.org", "we", "our", or "us") provides free online calculators, mathematical models, worked examples, and scientific guides. By accessing or using any part of this website, you confirm that you have read, understood, and agreed to these Terms of Service, along with our Privacy Policy. If you do not agree to these terms, you must discontinue use of the site immediately.
2. Educational & informational purpose only
All content on Biology Calculator—including mathematical calculations, biological estimates, dosage models, gestation forecasts, and reference tables—is published strictly for general educational, academic, and informational purposes. Our tools show the science, formulas, and published literature behind biological calculations; they do not provide individual diagnostic, medical, clinical, or commercial agricultural recommendations.
3. No veterinarian-client or doctor-patient relationship
Use of this website does not establish a Veterinarian-Client-Patient Relationship (VCPR) or any confidential clinical relationship.
Calculators addressing companion animals, livestock, medication administration, or toxicity thresholds (e.g. canine chocolate toxicity, feline medication formulas, gestation predictors) are mathematical implementations of published veterinary literature. They are not a substitute for direct examination, diagnosis, or prescription by a licensed veterinarian.
Never give prescription medications (such as opioids, antibiotics, or non-steroidal anti-inflammatories) to an animal without express veterinary direction, prescription, and supervision. If your animal is showing acute distress, suspected toxicity, severe illness, or dystocia, contact an emergency veterinary hospital or animal poison helpline immediately.
4. Laboratory, forestry & agricultural disclaimers
Calculations in molecular biology (e.g., PCR annealing, serial dilutions, absorbance-based concentrations) and agronomy/forestry (e.g., fertilizer application, timber valuation, carbon sequestration) rely on standard published mathematical models and ideal conditions. Real-world laboratory yields, reagent purities, microclimates, soil chemistry, and timber defect factors will vary. Users are responsible for verifying all values and experimental protocols against their specific laboratory standard operating procedures (SOPs) or field analyses.
5. Accuracy and corrections
While every calculator and guide is curated by named domain specialists (Dr. Dinesh A. Nagegowda, PhD, and Dr. Chyrle Bonk, DVM) and cross-referenced with peer-reviewed literature, university extension bulletins, and official guidelines, we make no guarantees of mathematical perfection or ongoing completeness. When errata or updated biological standards emerge, we update equations promptly via our Corrections log.
6. Intellectual property and permitted use
The original text, explanations, formulas, diagrams, SVG graphics, and software scripts on Biology Calculator are protected by copyright. You may use our tools and cite our explanations for personal, non-commercial educational study, teaching, and academic research. Automated scraping, bulk copying of content without attribution, framing, or unauthorized redistribution of our code is prohibited.
7. Disclaimer of warranties & limitation of liability
THE SITE AND ALL CONTENT, CALCULATORS, AND SERVICES ARE PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL BIOLOGY CALCULATOR, ITS OPERATORS, AUTHORS, EDITORS, OR AFFILIATES BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING FROM OR RELATING TO YOUR USE OF, OR INABILITY TO USE, THIS SITE OR THE CALCULATIONS PROVIDED HEREIN, INCLUDING BUT NOT LIMITED TO ANIMAL INJURY OR DEATH, CROP LOSS, LABORATORY ERROR, OR BUSINESS INTERRUPTION.
8. Third-party links & advertising
This website contains hyperlinks to third-party academic repositories, university extensions, government agencies (e.g., USDA, CDC, NIOSH), and external service providers. We do not control or endorse the content or practices of third-party websites. Advertisements on this site may be served by third-party ad networks, including Google AdSense; ad serving is governed by our Privacy Policy.
9. Modifications to terms
We reserve the right to revise or replace these Terms of Service at any time. Changes will be posted to this page with an updated modification date. Continued use of the website following the posting of changes constitutes acceptance of those changes.
