Solve PV=nRT for pressure, volume, moles, or temperature. Includes unit conversions and gas constant options.

Calculate current using I=V/R. Enter voltage and resistance to get amps with common unit conversions.

Calculate electrical resistance using R=V/I. Enter voltage and current to get ohms with unit support.

Convert wavelength to frequency (and reverse) using f=c/λ. Supports nm–m and Hz–THz ranges.

Convert wavelength to photon energy using E=hc/λ. Supports nm, μm, m and outputs eV or joules.

Calculate velocity from distance and time, or using kinematics. Outputs m/s, km/h, mph with conversions.

Calculate acceleration using change in velocity over time, or kinematics formulas. Supports SI units and m/s².

Calculate pressure using P=F/A. Supports Pa, kPa, bar, psi, and unit conversions for force and area.

Calculate density, mass, or volume using ρ=m/V. Works for solids, liquids, and gases with unit support.
