Here is a List of Best Free Unit Converter Software for Windows. These freeware help you with unit conversion of various unit types or measurement categories. Unit conversion is necessary because it helps with carrying out formula based calculations. At times, the values provided for certain measurements are not in standard form, thus you need to convert them before calculations can be carried out.
These unit converter software let you convert units for a variety of measurement quantities. Some of these tools let you convert unit for standard measurement categories, like: Area, length, time, velocity, distance, temperature, mass, volume, angle, density, etc. Some include standard unit types along with not so common unit types, such as: Concentration, flow, energy, force, light, conductance, charge, radioactivity, charge, data transfer, etc.
In most of these unit conversion calculators, all you have to do is select a measurement category, then choose From and To units, and enter the value of the unit which you want to convert.
