Americans will really do anything to avoid using the metric system.
@drmaddkap Ah yes, the emperor penguin, a well known unit of measurement with which all people in North America will be intimately familiar.

... compared to, say, a "yard" (three foot long), which is almost as long as a meter. And many people have used "yard sticks" of that length. A "yard" is just over 8.5 cm short of a meter.

So about 24 yards wide, as a really rough number.

"Nearly to the 25 yard line on a football field" would do it!

@JeffGrigg @XanIndigo @drmaddkap I just aggressively swap meters and yards, it's almost always close enough for guesswork. Also being a difference of 2.54, you can guesstimate centimeters as being either 1/2 or 1/3 of an inch, whichever you feel like. Finally 1 mile is about 1½ km, a gallon is about 4 liters, and there's about 2 pounds per kg. 20°C is about room temperature, 10°C is jacket weather, & 30°C is beach weather.

Attempts at precision suck.

@wilbr @JeffGrigg @XanIndigo @drmaddkap What's wrong with using metric exclusively?
@drmaddkap @XanIndigo @wilbr @fschaap @JeffGrigg
There’s no metric time. So you have to do conversions anyway that aren’t powers of ten. At that point it makes no difference, so why change?

@YetAnotherGeekGuy @drmaddkap @XanIndigo @wilbr @fschaap @JeffGrigg

The second is the SI unit for time. There's no "metric" minutes/hours - we don't need them

@wilbr @Henrysbridge @drmaddkap @XanIndigo @fschaap @JeffGrigg
If you are going to simplify conversions to power of ten math … isn’t that the Metric System brand promise?

@YetAnotherGeekGuy @wilbr @drmaddkap @XanIndigo @fschaap @JeffGrigg

No. Just to clarify, SI is *a* metric system, not *the* metric system. (another example in wide use in science before SI was cgs, with the centimetre, gram and second as base units).
"metrication" after the French Revolution introduced metric time and the grad for angles. Neither caught on as they had no advantage over the "traditional" systems.

SI seeks to connect units to sound, universal standards.
