Units of Measurement
Units of Measurement Printable(** for Premium Members only)
What do inches, pints, centimeters, degrees, kilobytes and seconds all have in common? They are units of measurement. Learning when to use which unit, and how to convert from one to another is this week’s topic.
Convert Me has “interactive calculators for many measurement systems both commonly used like metric and U.S. Avoirdupois and quite exotic like Ancient Greek and Roman.” These calculators allow you to specify significant figures (which determines how much rounding is done), a feature not found on other sites. To use, first select the type of unit such as Weight and Mass, or Distance and Length. Enter the measurement you want to convert from (such as 1.5 pounds) and click Convert. You’ll get the conversion in all available units, such as .68 kilograms, 18 Chinese taels and 53 old Russian lots.
