We want to express 1451 feet in meter.
1451 ft≈ m
We can do this by using the fact that 1 foot equals about 0.30 meter. Let's write this relationship as a unit ratio.
0.30 m/1ft
To perform the conversion, we need to multiply 1451 feet by the unit ratio or its reciprocal. Remember, we want to get the height in meters, and every unit we do not want has to be divided out.
We found that the Willis Tower is about 435.3 meters high.
