Navigate to an online conversion chart. Locate the 10th on the chart to retrieve the corresponding number of minutes.
Navigate to an online converter. Enter the 10th of an hour into the "Hour" box. The minute conversion is automatically generated in the "Minutes" box. Once again, this minute value is an approximation because of rounding.
