Metric to English conversion is a good thing to practice.
"Metric conversion" refers to the change from English units of measurement to metric units.
There is no single conversion unless you consider a systemic to an evolutionary hotchpotch, mishmash as a conversion. There are different conversions for different measures.
First, there is no "English". Second, there are hundreds on conversion factors between the near-obsolete (conventional) and metric systems. For mass alone, for example, there are conversions from grain to milligram, ounce to gram, pound to kilogram, stone to kilogram, hundredweight to kilogram, Imperial ton to metric ton. There are more that these.
