Units Conversion Chart vs Precision Metric

Calculating unit conversion manually takes a lot of time, thats why we built this application to make units conversion simplier. It outputs accurate conversion values and includes both imperial and metric units. Designed to be user-friendly, allowing you to do the conversion and process the results straight forward. Allows to set the conversion of decimal range in settings and supports up to 24 points which will give the maximum output accuracy. Currently the application supports 23 different unit conversions and we will continue to put efforts to include more frequently used unit conversions in the upcoming versions.
