10 carefully crafted calculators and tools to help you with science
Acceleration Calculator
Calculate acceleration from a change in velocity over time (a = Δv ÷ t), or solve for final velocity, initial velocity, or time using v = u + a·t. Includes the displacement too.
Density Calculator
Calculate density from mass and volume, or find mass or volume from density. Handles grams, kilograms, pounds, litres, millilitres, cubic metres and more, reporting in both g/cm³ and kg/m³.
Energy Calculator
Calculate kinetic energy (½mv²), gravitational potential energy (mgh), and work done (F × d) in joules, with results also in kilojoules and calories.
Force Calculator
Calculate force from mass and acceleration with Newton's second law, or find the mass or acceleration from force. Switch acceleration to gravity to get an object's weight in newtons.
Ideal Gas Law Calculator
Solve the ideal gas law PV = nRT for pressure, volume, amount, or temperature. Enter the other three with flexible units (atm, kPa, bar; L, mL, m³; K, °C, °F) and get the answer in SI and everyday units.
Molar Mass Calculator
Type any chemical formula — including brackets like Ca(OH)2 — and get its molar mass in g/mol, a full element-by-element breakdown, and each element's mass percentage.
Ohm's Law Calculator
Solve Ohm's Law instantly — enter any two of voltage, current, and resistance and get the third, plus the power dissipated. Works in volts, amps, ohms, and watts.
pH Calculator
Convert between pH, pOH and hydrogen ion concentration [H⁺]. Enter any one value and get the rest, with an instant acid/neutral/base reading.
Pressure Calculator
Calculate pressure from force and area, or solve for force or area. Enter area in m², cm², in² and more, and read pressure in pascals, kPa, bar, atm, and psi.
Wavelength Calculator
Convert between wavelength and frequency using c = λf, with photon energy in joules and electronvolts. Enter a wavelength (in nm, µm, or m) or a frequency (Hz to THz).
Science is built on precise calculation. CalcPool's science tools apply established physics and chemistry formulas to real-world problems — showing the formula, the working, and the answer clearly. Whether you are solving a motion problem, converting units, or working out the pH of a solution, every tool is designed to be both accurate and understandable.
Why Use CalcPool Science Tools?
Formula-first approach
Every tool shows the scientific formula it uses before displaying the result. You always know exactly what equation is being applied to your inputs.
Plain English explanations
Scientific tools should be accessible, not intimidating. Every tool includes a plain-language explanation of what the formula means and why it matters.
Expanding library
New science calculators are added to CalcPool weekly. If there is a specific tool you need, use the contact form to suggest it.
