About Chemistry Tools
Chemistry Tools provides free calculators, reference tables, and study support for university students, pre-med students, and chemistry learners worldwide. Every tool is built around the same goal: show the formula and the working, not just the final number, so the calculator doubles as a study aid.
Who Builds This Site
Chemistry Tools is developed and maintained by Muhammad Kashif and Nur Syaza Sahira Binti Ahmad Zaidi. The calculators are organized around standard chemistry workflows, textbook formulas, and student-friendly explanations across general, analytical, physical, and organic chemistry.
Editorial Standard
Calculators use standard textbook equations and IUPAC atomic masses, with assumptions stated on each tool page. Reference notes cite the underlying relationships so students can verify every step by hand. When a tool is still in preparation, its page is clearly labeled as a study guide rather than a live calculator.
What You Can Use Today
13 live calculators including the molecular weight calculator, chemical equation balancer, and pH calculator, plus an interactive periodic table, study guides, and lab reference notes.
