This converter requires the use of Javascript enabled and capable browsers. This script converts nautical depth in one designation to the other two. The designations are feet, meters and fathoms. There are three converters, each doing a "FROM" conversion. Enter a value in the required entry field, or accept the default value of 1. Then click on Convert to display the other values. To do another of the same designation but with different values, click the Clear Values button and then enter a new value. To do one of the other designations, scroll down to the value you know in order to find the other two. Calculated accuracy of current Javascript enabled browsers is 16 places.
