This app is designed to aid in cross-unit calculations between Standard and Metric units. With the "Calculator" tool you can execute calculations across standard decimal and fraction values (in inches), as well as metric values (in millimeters). In Addition, you can tap on any value in the "transcript" output to see its equivalent in the alternate unit type/style. If you tap the icon next to a value you can add that value to the "Pins" view, which can be seen by tapping the icon in the lower right portion of the transcript view. With the "Convert" tool you can select one of three input fields (millimeter, standard decimal, or standard fraction) and type in a value to get an instant conversion into the other two unit types. The "Table" tool is a simple table with common measurements converted between metric and standard (decimal & fraction). This app is a work in progress with more features to come! Feedback and feature suggestions are welcome.
