Periodic tables, chemistry, physics and learning aids.
Education Tools
GPA, grades and study tools.
CGPA to Percentage Converter (Indian Universities)
Convert CGPA (10-point) to percentage by university — VTU, Anna, Mumbai, Pune, AKTU, CBSE, Delhi. Each uses a slightly different formula.
Final Exam Grade Needed Calculator
Find out the exact score you need on your final exam to hit your target grade. Just plug in your current grade, target grade and final's weight.
GPA Calculator
Calculate your GPA on a 4.0 scale — add unlimited courses with credits and grades.
Science Tools
Chemistry and physics utilities.
Virtual Chemistry Reactor
A three-mode educational chemistry simulator: mix any of the 118 elements and 50+ common compounds in an animated reactor vessel. Beginner mode tells the story of each reaction; Advanced adds real stoichiometry with limiting reagents and yields; Scientist unlocks ΔH energies, redox half-equations and reaction conditions. Built on a database of 150+ verified, balanced reactions — with honest labels when a combination is predicted or simply doesn't react.
Interactive Periodic Table
Click any element to see its atomic mass, group and properties.
Reference and study aids for STEM and school
This corner serves two audiences: students checking grades and curious minds poking at chemistry and physics. The tools are interactive rather than static reference pages — you click an element and see its data, or enter your marks and watch a GPA fall out. That makes them useful for both homework and genuine exploration.
The Interactive Periodic Table is a clickable, searchable table with each element’s atomic data, while the Virtual Chemistry Reactor lets you combine reactants and see the products. On the academic side, the GPA Calculator handles 4.0, 5.0 and 10.0 scales with per-semester breakdowns, the Final Exam Grade Needed Calculator tells you the score you must hit, and the CGPA to Percentage Converter handles Indian university conversions.
Who uses this and why:
- Students computing GPA, CGPA or the grade needed on a final
- Chemistry learners looking up element properties
- Experimenting with reactions in a safe virtual reactor
- Converting an Indian CGPA to a percentage for applications
