Miles and Kilometers
You can convert miles to kilometers or the reverse and subsequently miles/
hour to kilometers/hour and the reverse.
1. Rotate the inner scale until the «STAT» arrow is set opposite the number of
miles you want to convert to km on the outer scale.
2. Read the corresponding km value on the outer scale that is set opposite the
«MPH/KM» arrow on the inner scale. (e.g., to convert 25 mph to kilome-
ters per hour, set the STAT arrow opposite 25 on the outer dial. The MPH/
KM arrow is pointing to 40 which indicates 25 MPH = 40 K/H.)
3. To convert from miles to km, do the reverse.
