UNIT
Use the UNIT command to select metric or non-metric output units:
UNIT [x]<cr>
where
x = M or N
where
M = Metric units
N = Non-metric units
NOTE This command changes both the serial output and display units to either
metric or non-metric units. When you want to output both metric and
non-metric units simultaneously on the serial line and display, select the
display units later by using the display/keypad.
