Still think that unit conversion isn't important? Here is a widely publicized, true story about how failing to convert units resulted in a huge loss. In 1998, the Mars Climate Orbiter probe crashed into the surface of Mars, instead of entering orbit. The resulting inguiry revealed that NASA navigators had been making minor course corrections in SI units, whereas the software written by the probe's makers implicitly used British units. In the United States, most scientists use Sl units, whereas most engineers use the British, or Imperial, system of units. (Interestingly, British units are not used in Britain.) For these two groups to be able to communicate to one another, unit conversions are necessary. The unit of force in the SI system is the newton (N), which is defined in terms of basic Sl units as 1 N=1 kg · m/s?. The unit of force in the British system is the pound (lb), which is defined in terms of the slug (British unit of mass), foot (ft), and second (s) as 1 lb =1 slug ·…

Earth is on average a distance of 2.25 x 1011 m away from Mars. If a radio signal is sent from Earth traveling at a speed of 3.0 x 108 m/s, how many seconds would it take to be received on Mars?
a) A typical small passenger electric vehicle has a range of 200 km on an electric charge of 33 kWh. Convert this number into J/km (Joules per kilometer traveled). b) A comparably sized gasoline powered vehicle to (a) is rated as 25 miles per gallon. Convert this number into J/km (Joules per kilometer traveled). c) If gasoline costs $10.00 per gallon, and electricity $0.30 per kWh what is the difference in the cost of fuel per kilometer travelled between the electric vehicle in (a) and the gasoline powered vehicle in (b)? d) Surveys of EV owners show that they charge at home 70% of the time. Let us assume that for the remaining 30% they charge at a 60 kW rated "fast-charge” station. If patterns of travel remain the same, but we swap all our gasoline vehicles for electric vehicles, what is the ratio between installation of fast charging stations to gasoline pumps retired. e) The Chicago Transit Authority has about 2700 buses that travel a total of 240,000 miles daily.
