A tool can belong to several categories. All tools lists each calculator once.
Mathematics
Logarithm Calculator
Learning & Education · Science & Lab · IT & CommunicationCalculate a real logarithm in any valid base, or raise that base to an exponent. Compare natural, binary and decimal logarithms and inspect the inverse relationship.
Open calculator ↗Complex Number Calculator
Learning & Education · Science & LabAdd, subtract, multiply or divide two complex numbers. Enter real and imaginary parts separately, then inspect magnitude, argument and an equal-scale complex-plane diagram.
Open calculator ↗Vector Calculator
Learning & Education · Science & Lab · Design & DrawingEnter two three-component vectors to calculate their sum, difference, dot product, cross product, magnitudes and angle, with an XY-projection diagram.
Open calculator ↗Work Rate Calculator
Time & Planning · Learning & Education · Science & LabCalculate how long two constant-rate workers, machines or pipes take together. Include an opposing drain and an already-completed fraction, with a progress graph.
Open calculator ↗Weighted Average Calculator
Learning & Education · Money Management · Science & LabEnter paired values and weights to calculate a weighted mean. Inspect normalized weight shares, each contribution and a comparison with the unweighted average.
Open calculator ↗Linear Interpolation Calculator
Learning & Education · Science & Lab · Design & DrawingEnter two known points and a target x or y. Calculate the other coordinate, view the straight-line model and clearly distinguish interpolation from extrapolation.
Open calculator ↗Physics
Series and Parallel Resistor Calculator
Learning & Education · Science & LabFind the equivalent resistance of 2–20 ideal resistors in series or parallel. Enter a DC voltage to calculate current, voltage drop and power for every resistor.
Open calculator ↗Kinetic Energy Calculator
Learning & Education · Science & Lab · Automotive · Sports & FitnessFind translational kinetic energy, mass or speed from the other two values. Choose explicit units, compare energy equivalents and see how energy changes with speed.
Open calculator ↗Pressure Converter
Learning & Education · Science & Lab · Construction & DIY · AutomotiveConvert pressure across SI and other common units. Distinguish absolute and gauge readings using a reference pressure you enter, and compare both in a unit table.
Open calculator ↗Temperature Converter
Learning & Education · Science & Lab · Cooking & Kitchen · TravelConvert Celsius, Fahrenheit, kelvin and Rankine. Distinguish actual temperatures from temperature changes, and compare all four scales in a table.
