Convert "4 miles" to "pounds" by multiplying by unit fractions which change the units but keep the measurement the same.

As an example of this, you can change "5 feet" to inches by multiplying by the unit fraction "12 inches/1 foot". 12 inches is equal to 1 foot, so the multiplication changes the units without changing the measurement.
             12 inches
   5 feet * ----------- = 60 inches
              1 foot

Using the appropriate unit fractions to convert "4 miles" to "pounds"...:
              5280 feet     12 inches       1 penny       0.0875 ounces     1 pound
   4 miles * ----------- * ----------- * ------------- * --------------- * ------------
                1 mile       1 foot       0.75 inches        1 penny        16 ounces

Multiplying all that out, you should find that 4 miles of pennies weighs less than a ton, which is 2000 pounds.

If it's not homework, what is it?
Idle curiosity?
Or do you have miles of pennies?

Some candidate for prez finally said to eliminate the US pennies.
Why not? It costs more than a penny to make one, and they almost worthless.
