Where you gonna go to figure out how many liters are in a gallon? Or how many teaspoons, ounces or hogsheads, for that matter? This site’s slogan is “Convert just about anything to anything else.” And it’s not kidding. For instance, a city block in the Western United States is nearly 44 “mark twains” long or 88 fathoms (back East, city blocks are half as long). And the Julian date for January 1 of this year was 2453737. Or try some of the calculators under “fun stuff.” Among other things, you can learn your weight on other planets or translate words into Morse code and whole numbers into Roman numerals (and vice versa). You can convert your clothing and shoe sizes into units used in other countries, though that’s mostly depressing. Your weight on Pluto will be a more uplifting number.
