"Prepare to be amazed" - AJ Batac (/-_-) from Bookmarklet

Har! I remember when they were prepping us for it in the '70s. Gas pumps all had gallons and liters on them for a while. Then Reagan was elected... - Spidra Webster

Great.....Nice way to call us out. Haha - Shevonne

Do the other three all use the same system or each their own? - Skyler Call

I think the U.S. and Liberia use the same system, but Burma has their own - Victor Ganata from iPhone

So, America, we Brits have something of a confession to make. We might SAY we're all "kilometers" and "kilograms", but we all still think in pounds and miles. We teach our kids about both systems because their parents still use the old ways. Personally, I use whichever comes nearest to a whole number when I'm working. This means that I'm often building stuff that measures "6 foot 3 inches by seventeen-hundred millimetres" - Slippy Lane

I wonder why Alaska is marked in as a country ! - Peter Dawson

Have any spacefaring nations besides the U.S. ever lost entire spacecraft due to using the wrong system of measurements? - Victor Ganata from iPhone

The elite - RAPatton from iPhone

Victor, technically the British. Weren't they on the other end of that debacle? (And, for the record, it's why F# introduced a syntax specifically allowing for the specification of units of measure as a strong type against any numeric.) - Akiva

Peter, it's part of the United States. Note too that Hawaii is in red. - Akiva

Lately, the most important unit of measure for me is PIXELS. - Micah

TWSS? - WoH: Minding her Steves

I still use a weird mixture of the two, even after so many years. Indoor temperatures are °F and outdoors °C. My gas consumption is mpg yet I measure distance in km. I weigh 200 lb but buy steak in kg. And if I'm cutting lumber I still work in ft and inches. My kids though are pretty much all metric. Maybe it takes a generation? - Ken Morley

It definitely takes a generation, in my opinion. If we'd started in the '70s, I'd be doing that conversion thing but my youngest siblings (about 20 years younger than me) wouldn't know much else. Same way they don't know how to use a record player or dial style phone. - Spidra Webster

The Imperial Empire: The US, Liberia, & Burma LMAO; time for change - sofarsoShawn <Oh HAI!>

Hmm, I hadn't remembered about the 1999 orbiter mission http://articles.cnn.com/1999-09... and it's strange that they talk about 'English' units. England used the 'Imperial' system but metrication started in 1978 and with pre-packed foods being sold in metric amounts. Then in 2000 all loose measurements *had* to be in metric (which still caused an outcry even after all the years of having metric measurements all over the place). - WoH: Minding her Steves

Burma has their own indigenous unit system. - Victor Ganata

Canadians use a mixed system too. Gasoline in liters, milk in liters, fish often (not always) in grams, human dimensions (height, weight) in feet and pounds, housing usually in square feet, distance in kilometers... - Andrew C (✓)
