- Ohm's Law CalculatorSolve for voltage, current, resistance, or power from any two known values, with the exact formula used and the full Ohm's law wheel explained.
- Electricity Cost CalculatorWork out what an appliance costs to run per hour, day, month, and year from its wattage, usage hours, and your electricity rate per kWh.
- Dew Point CalculatorCalculate dew point, absolute humidity, and how the air will actually feel from temperature and relative humidity, in Celsius or Fahrenheit.
- Molecular Weight CalculatorCalculate molar mass from any chemical formula, with per-element percent composition and a grams-to-moles conversion.
- Molarity CalculatorCalculate the molarity of a solution from mass, molar mass, and volume — or find the mass of solute needed to make a solution of a target concentration.
- Half-Life CalculatorCalculate how much of a substance remains after any time using exponential decay, from its half-life — plus the decay constant, mean lifetime, and number of half-lives.
- Specific Heat CalculatorFind the heat energy needed to change a substance's temperature with Q = mcΔT, using a built-in table of specific heat capacities or your own value.
- pH CalculatorConvert between hydrogen-ion concentration and pH, with pOH and hydroxide concentration, and see where a solution falls on the acidic–neutral–basic scale.
- Dilution CalculatorWork out how much stock solution and diluent to mix for a target concentration and volume using C₁V₁ = C₂V₂, with the dilution factor and fold dilution.
- Wind Chill CalculatorCalculate the wind chill or 'feels like' temperature from air temperature and wind speed using the official NWS formula, with the frostbite risk it implies.
- Percent Yield CalculatorCalculate the percent yield of a reaction from the actual and theoretical amounts of product — the standard measure of reaction efficiency — in grams or moles.
- Boyle's Law CalculatorApply Boyle's law, P₁V₁ = P₂V₂, to find the new pressure or volume of a fixed amount of gas at constant temperature when the other changes.
- Moles CalculatorConvert between grams, moles, and number of particles using molar mass and Avogadro's number — the core mass-to-moles conversion of chemistry.
