Teams learn about the size of a nanometer by measuring objects and converting those measurements. A worksheet then tests the groups' abilities to use nanometers by having them determine the size of objects that are too small to...

The incredibly shrinking meter—decimeters to centimeters, to millimeters, and now to nanometers! Learners may have a difficult time visualizing particles on a nanoscale. Help them see a little clearer using a well-designed lesson...

Have you ever wondered how many ants make up an elephant? Inquisitive minds will be amazed as they use scientific notation to compute and compare the mass of an elephant to an ant. Have participants make guesses and see how close they...

With minimal setup and maximum freedom, young geometers are encouraged to think outside the box on a seemingly simple application problem. Though the task seems simple, measuring a given paper clip and finding how many 10 meters can...

Chart your way to an understanding of nanoscale. Using a Google map, learners estimate a radius around their location of 1,000 and 1,000,000 meters. Predicting what 1,000,000,000 meters would look like takes them off the charts!...

Don't let your eyes play tricks on you ... use scale to keep your eyes in check! Young scholars observe images without scale and try to identify the structure. Then, they look at the same image with a scale bar and assess whether their...

Take your class out to visit your automobile and use the tires to compute the weight of the vehicle. This is done by measuring the surface of the tire meeting the ground and the air pressure. This is a fun lesson in the relationship...

You don't need a scale to determine weight. This activity provides a way to use the concepts of air pressure and surface area to determine the weight of a vehicle by calculating the amount of weight each tire supports.

Use this converter to find equivalent units for a measure. You can convert measures for area, length, weight, temperature, and volume.

Test your knowledge at metric conversion by answering 30 questions on distance, length, volume, and weight.

Two sample problems with show you how to convert between meters and kilometers. Click on the conversion chart for more help.

This site gives conversions from metric to metric as well as providing abbreviations for each.
