Acceleration Calculator
Find acceleration, final velocity or time from a = (v_final − v_initial) ÷ time.
Dilution Calculator
Solve the dilution equation C₁V₁ = C₂V₂ for any unknown — how much stock and diluent to reach a target concentration.
Force Calculator
Apply Newton’s second law F = m × a: enter any two of force, mass and acceleration to find the third.
Gear Ratio Calculator
Find the gear ratio from the driving and driven tooth counts, plus the output speed and torque multiplier.
Kinetic Energy Calculator
Calculate kinetic energy KE = ½ · m · v², or solve for the mass or speed from the energy.
Molarity Calculator
Find molarity, mass or solution volume from the relation molarity = mass ÷ (molar mass × volume).
Momentum Calculator
Compute linear momentum p = m × v, or solve for the mass or velocity from the other two.
Ohm's Law Calculator
Apply Ohm’s law V = I × R: enter any two of voltage, current and resistance to get the third plus the power (W).
Percent Error Calculator
Calculate percent error between a measured value and the accepted value: |measured − accepted| ÷ |accepted| × 100.
Pressure Calculator
Apply P = F ÷ A: enter any two of pressure, force and area to find the third, in pascals.
Speed Calculator
Work out speed, distance or travel time from the other two using speed = distance ÷ time.
Torque Calculator
Calculate torque τ = F × r × sin(θ), or solve for the force or lever arm — with the angle between them.
Wavelength Calculator
Convert between wavelength, frequency and wave speed using v = f × λ — for light, sound or any wave.
