How to interpret and use "ratio units"--units that form ratios, such as "meters/second" or "kilograms/cubic meter" or "newtons/coulomb". Some other common examples of ratio units are watts (joules/second), volts (joules/coloumb), and molarity (moles/liter).The videos should help you to understand and work with concepts such as electric field, electric potential, density, power, concentration, and many other concepts in physics and chemistry that have ratio units. "Ratio units" are important in many other fields--such as economics and finance--as well.These videos are offered on a "pay what you like" basis.
