WinConverter is a rather straightforward application which is designed to provide as simple interface as possible for performing unit conversion. WinConverter 3.1 is pre-configured to convert 1500 units in 78 categories. If you find out WinConverter lacks a unit you need it is very easy to add your custom unit or category.The predefined categories include:Mass Length Time and Volume. Acceleration - Linear Area Data Storage Data Transfer Energy Flow Force Numbers Power Pressure Temperature Velocity Acceleration - Angular Angle Calorific Value Concentration - Liquid Solution Concentration - Molar Density Digital Image Resolution Entropy EU Currency Flow - Mass Flow - Molar Frequency Wavelength Fuel Efficiency Heat Capacity Heat Flux Density Heat Transfer Coefficient HVAC Efficiency Chemical - Henrys Law Illumination Illumination - Luminous Intensity Latent Heat Luminance Mass Flux Density Moment of Inertia Permeability Radiation Radiation - Absorbed Dose Radiation - Activity Radiation - Exposure Sound Specific Heat Specific Volume Surface Tension Temperature Interval Thermal Conductivity Thermal Expansion Torque Typography Velocity - Angular Viscosity - Dynamic Viscosity - Kinematic Volume - Dry and Volume - Lumber.
