Convert Me5 stars

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.

CyberSleuth Kids: Units of Measurement Worksheets3 stars

These twenty-three printable worksheets for elementary ages provide practice for converting units of length (mostly) and units of weight (just a few.) The worksheets are not labeled, so you will need to click on each image to see what it covers. Topics include millimeters to centimeters, inches to feet, feet to yards, ounces to pounds, and vice versa. To print the pages without headers and footers, remove them in your browser's Page Setup dialog.

EdHelper: Measurement Worksheets5 stars

Despite the title, this EdHelper page is not just worksheets, but a collection of puzzles, word stories, charts and lesson plans, all related to units of measurement. English length, weight, capacity, time and temperature are covered on this table of contents. Metric units are covered on a separate page (look for the Also Visit link. ) Some of the worksheet links only provide a single printable worksheet, while others allow you to generate an unlimited number of handouts and answer keys. Although paying members get even more worksheets, there is enough free content to earn a five-star rating.

To use, select the units you want converted from and to (such as knot to mach) from the drop-down lists. Results are rounded to seven decimal places. In the Fun Stuff category, you'll find Roman Numeral conversion, a Pig Latin translator, typing speed test and much more.
