Unit converter

Convert everyday, design and engineering measurements. Choose a measurement type, then select either unit freely. Electricity includes voltage, current, resistance, charge, capacitance, inductance, conductance and resistivity. Power, energy, force, torque, density, fuel economy and other quantities have their own types. Edit either value; the other updates automatically.

CSS pixels describe layout: 1 inch is defined as 96 CSS pixels. Rem uses the root font size, em uses the element font size, and viewport units use the supplied viewport. Image pixels describe a raster file: its print size depends on PPI, commonly 300. Neither mode measures the physical size of your screen.
