Calculators by Course: Engineering, Statistics, Algebra, Chemistry & Finance
Browse calculators by university course, from Statics and Thermodynamics to Introductory Statistics and General Chemistry, or plan your grades, GPA and credits. All free, no signup required.
Core subjects
These collections support first-year courses outside engineering: Introductory Statistics, College Algebra and Precalculus, General Chemistry and Business Finance. Each follows a topic path through selected calculators and says what its tools do not cover. 9 of these calculators open with a worked example: load it into the tool, change one input and predict the result before you reveal it. Check your syllabus for course coverage.
Describe data, explore probability, estimate uncertainty and compare means.
Explore lines, quadratic roots, inequalities, exponents and logarithms.
Work with moles, concentrations, reaction yields and titration stoichiometry.
Compare cash flows, interest rates, investment value and operating break-even.
Student planning
Plan your remaining assignment scores, a final-exam target, your cumulative GPA and the credits left in your degree. Results are scenarios, not official grades: use your syllabus and your institution’s rules.
Engineering courses
MegaCalc organizes its engineering calculators by the undergraduate and graduate mechanical engineering courses where they are most useful. Whether you are preparing for an exam in Thermodynamics, working through a problem set in Fluid Mechanics or reviewing Statics and Dynamics before a design project, each class page brings together the calculators and reference tables for that course, grouped by the topics your textbook covers.
The engineering curriculum is broadly divided into three pillars: solid mechanics (Statics, Dynamics, Mechanics of Materials, Vibrations), thermal sciences (Thermodynamics, Fluid Mechanics, Heat Transfer) and applied design (Machine Design, Materials Science, Manufacturing, Controls). The calculators implement standard textbook equations from widely used references (Hibbeler, Cengel, Crandall, Shigley, Bergman), and some show the formula they use; the methodology page explains how they are checked. Students preparing for the FE (Fundamentals of Engineering) exam or PE (Professional Engineer) licensure can use them to verify hand-calculated answers.
