Free Academic Study Tools
Instant, ad-free browser utilities and honest AI workflow hubs for STEM labs, essays, citations, and exam prep—built to save you hours every week.
Scientific Notation & E-Notation Converter Calculator
Enter any decimal or E-notation number (like 0.0000452 or 6.022e23) to convert instantly between Scientific Notation (a × 10ⁿ), Engineering Notation (10³ⁿ), and standard decimal form.
Test Grade Percentage & Curve Calculator (EZ Grader)
Enter the total number of questions on your test and how many you missed to see your exact percentage, letter grade, nearby score table, and optional flat or square-root grade curve.
Step-by-Step Quadratic Formula & Discriminant Calculator
Enter coefficients a, b, and c for ax² + bx + c = 0 to see the exact discriminant (Δ = b² - 4ac), real or complex roots, step-by-step substitution, and parabola vertex.
Molar Mass Calculator & Grams-to-Moles Converter
Type any chemical formula—including parentheses like Ca(OH)2 or Al2(SO4)3—to calculate exact molar mass in g/mol, element mass percentages, moles, and molecules.
Significant Figures Counter, Rounding & Scientific Notation
Never lose lab points on rounding again: enter any chemistry or physics measurement to count significant figures, round to N digits, and convert into scientific notation.
