Visualize measurements with SensibleUnits

Ever experienced asking someone how far it is to the next station and their answer is about 2 kilometers? Since you don't want to be embarrassed, you just nod your head pretending that you got it. Or maybe you're looking for a place to rent but don't have any idea just how big 50 square meters is? Here's a great site that can help you achieve decent estimates.
SensibleUnits is a web utility that converts boring units to real life objects to help you better visualize measurements. So that 2 kilometers is about 40 olympic-sized pools.

You can still use the site to convert units to different measurements as well though if you're the boring type.
