Science Calculators
15 calculators
Textbook physics and chemistry: dilution, half-life, heat transfer, friction, ideal-gas behaviour and kinematics. The formulas are the standard closed-form classroom versions, which means idealised conditions — no heat loss to the container, no friction beyond the coefficient you entered. Laboratory work needs the measured value.
- Dilution Calculator Work out how much diluent to add to reach a target concentration using C1V1 = C2V2.
- Friction Calculator Calculate friction force, normal force and the force needed to move an object.
- Half-Life Calculator Calculate how much of a substance remains after a given time, or how long decay takes.
- Heat Transfer Calculator Calculate the energy, power and flow needed to change an object's temperature.
- Ideal Gas Law Calculator Solve the ideal gas law for pressure, volume, moles or temperature.
- Kinematic Velocity Calculator Calculate final velocity, displacement and average velocity from acceleration and time.
- Molarity Calculator Convert mass, molar mass and volume into molarity, moles and millimolarity.
- Momentum Calculator Calculate momentum for two objects and the combined velocity after a collision.
- Ohm's Law Calculator Enter any two of voltage, current and resistance to get the third plus power.
- pH Calculator Estimate pH from the concentration of a strong acid or base using a 25°C ideal-solution approximation.
- Projectile Motion Calculator Calculate range, maximum height and flight time for a projectile launched at an angle.
- Specific Heat Calculator Work out the heat energy needed to change the temperature of a material, using Q = mcΔT.
- Speed of Sound Calculator Calculate the speed of sound in air at any temperature, plus common media.
- Spring Constant Calculator Calculate a spring constant from force and extension, plus its period of oscillation.
- Wavelength to Frequency Calculator Convert between wavelength and frequency for light, sound or any wave speed.

Science tools apply a particular equation to a set of supplied quantities. Selecting the equation is part of the task: a motion problem needs a defined direction and time interval, while a solution calculation needs the appropriate concentration and volume convention. Keep units explicit throughout.
Choose a motion or energy relationship
Use momentum for mass and velocity, projectile motion for an idealized trajectory, and heat transfer or specific heat for the stated thermal model. A simplified equation can deliberately omit effects that matter in an experiment or design.
Work with solutions and circuits
Molarity and dilution use different descriptions of a solution. Ohm’s law relates electrical quantities under its stated model. Convert units first when the page requires a particular unit rather than assuming every field accepts any scale.
Check the model before using the number
Record the assumed conditions, significant figures and units with the result. A calculator does not validate an experimental procedure, chemical compatibility, electrical safety or a design’s compliance with a technical standard.
