Example 1-2: The 8000-m peaks. The fourteen tallest peaks in the world are referred to as “eight-thousanders,” meaning their summits are over 8000 m above sea level. What is the elevation, in feet, of an elevation of 8000 m?
A powerful way to check your calculation is to use unit analysis
Not only must the numerical values on both sides of an equation be equal, the units must be equal as well
Dimensions Dimensions of a quantity are the base units that make it up; they are generally written using square brackets. Example: Speed = distance/time Dimensions of speed: [ L / T ] In dimensions, mass, length, time, temperature, and electric current is symbolize with M, L, T, K and A respectively.
