Cruising altitude The cruising altitude is 1,000 feet We’re changing from a U.S length unit to a metric length unit. In the “U.S. to Metric Units” side of the table, you see that 1 foot = 0.30 meter. Two unit fractions can be written using that information.(1 foot)/(0.30 meter) Or(0.30 meter)/(1 foot). Multiply by the unit fraction that allows you to divide out feet (that is, feet is in the denominator). 1,000 ft *(0.30 meter)/(1 foot) = 300 meters
