🌍 Why We Built This

We noticed that many existing chemistry calculators are either inaccurate, overloaded with intrusive ads, require expensive subscriptions, or are not mobile‑friendly. PakChemHub Pro is our answer – completely free, scientifically accurate, and optimized for all devices.

👨‍🔬 Our Team

We are a small, passionate team of chemistry researchers and web developers dedicated to science education. We are not a large corporation – just scientists who want to help fellow scientists and students.

📊 Data Sources & Accuracy

All chemical data (molecular weight, formula, density, GHS hazards) is fetched in real time from PubChem (NIH). For common chemicals, we also maintain a local database for instant results. Our calculation algorithms follow IUPAC standards.

🔒 Privacy Commitment

We do not collect, store, or share any personal information. All calculations happen directly in your browser – no data is sent to our servers. We use Google AdSense to keep the service free, but you can opt out of personalized ads at any time.

📬 Contact & Feedback
