Have you ever wondered what is the biggest or the smallest or the tallest or the fastest or the heaviest anything in the world? Well, The Guinness Book of World Records keeps track of exactly those types of things, and the metric system factors into the world of the “officially amazing” as well!

#### News You Can Use

Because The Guinness Book of World Records tracks and records amazing feats from all over the world, the Guinness organization uses the metric system, as you can see in the certificate above. Though you will occasionally also see measurements in U.S. customary units (feet, inches, miles, pounds, etc.), you’ll always see the statistics in The Guinness Book of World Records in metric units. Understanding equivalent metric units of mass, length, and capacity can help you better grasp the mind-blowing nature of the records!

Now lets think about meters for a minute. If an entry in The Guinness Book of World Records states that the record is 36 meters, would you know how many centimeters that is? How about millimeters?

36 meters = 3,600 cm

36 meters = 36,000 mm

There actually is an entry in which the record is 36 meters. Find out what it is in this video: http://www.youtube.com/watch?v=BL7tvYnPsLs
