Frequently Asked Questions About Unit Conversion Math
What is a conversion factor and how does it work?
A conversion factor is a ratio that equals 1 and helps convert between units. For example, 1 inch = 2.54 centimeters is a conversion factor that helps change inches to centimeters or vice versa.
Why do units cancel in conversion calculations?
Units cancel in conversions because conversion factors are set up as ratios where the numerator and denominator are equivalent. When you multiply by these ratios, matching units divide out algebraically.
How do I learn dimensional analysis?
Start with simple conversions and practice setting up your calculations so units cancel properly. Use our conversion tools to check your work as you learn.
What's the easiest way to set up unit conversions?
Write down your starting measurement, then multiply by conversion factors that will cancel your original units and give you the desired units. Use our tools to verify your answers.
