Calculate force, mass, or acceleration using Newton's second law: F = m × a.

Calculate velocity, distance, or time using v = d/t. Convert between m/s, km/h, mph, and knots.

Calculate molarity (mol/L) from moles and volume, or required moles/grams for a target solution.

Calculate pH from hydrogen ion concentration, or compute [H⁺] and [OH⁻] from a known pH.

Calculate acceleration from initial velocity, final velocity, and time. Plus distance traveled.

Calculate density (ρ = m/V), mass, or volume. Convert between g/cm³, kg/m³, and lb/ft³.

Solve PV = nRT for any one variable. Useful for chemistry, engineering, and atmospheric science.

Calculate wavelength, frequency, or wave speed using v = f × λ. Light, sound, and any wave phenomenon.

Calculate voltage, current, resistance, or power using Ohm's law: V = I × R and P = V × I.
