Unit conversion problems constitute the first week of nearly every science course. Measurement is a basic skill in science, but not all measurement methods are the same. People measure the same thing in different ways and use different units. To communicate between scientists, there has to be a method of converting between the different measurement units.
This is a collection of unit conversion example problems to help you learn the general method and mindset of converting units. Most of these include an example going the opposite direction (for example: cm to m and m to cm).
How to Do Unit Conversions
Use the ladder method or dimensional analysis to tackle conversions between units. See how to use a conversion factor to step-by-step reach the desired end units. This method is especially useful for measurements with more than one conversion like kilometers/hour to meters/sec.
The L/min to m3/hr Conversion Example is a conversion example which uses the Ladder Method.
