2: Working with and Converting Measurements

( \newcommand{\kernel}{\mathrm{null}\,}\)

  • 2.1: The US Measurement System
    This system used to be called the English system, but now the U.S. has the dubious honor of being associated with the system that uses inches, feet, miles, ounces, pounds, cups, gallons, etc. To convert from one unit to another, we often have to perform messy calculations like dividing by 16 or multiplying by 5,280.
  • 2.2: The Metric System
    The metric system was first implemented following the French Revolution; if we’re overthrowing the monarchy, why should we use a unit of a “foot” that is based on the length of a king’s foot?
  • 2.3: Converting Between Systems
    Converting between the U.S. system and metric system is important in today’s global economy; like it or not, the metric system is infiltrating our lives.
  • 2.4: Conversions with Time
    This page provides insights on converting measurements of time and rates, highlighting the complexities due to the variability in days across months and years. It includes conversion factors for various time units and exercises on calculating time in minutes for a year and a lifespan of one billion seconds. Additionally, it features exercises related to Usain Bolt's sprint speed and an F-15 fighter jet, focusing on averages, distances, and fuel efficiency.
  • 2.5: Converting Units of Area
    Converting between units of area requires us to be careful because square units behave differently than linear units.
  • 2.6: Converting Units of Volume
    Just as we saw with area, converting between units of volume requires us to be careful because cubic units behave differently than linear units.
