“King Henry Died By Doing Crystal Meth” (metric mnemonic)

“King Henry Died Monday Drinking Chocolate Milk” is a mnemonic device for remembering the metric units, in descending order: kil-, hecto-, deka-, meter-, deci-, centi-, milli-.

The “M” for “meter” (or “Monday") is sometimes replaced by “U” for “unit” or “B” for “base unit,” so that the mnemonic can be used for meters, grams and liters. “King Henry Died Unexpectedly Drinking Chocolate Milk,” “King Henry Doesn’t Usually Drink Chocolate Milk” and “King Henry Died By Doing Crystal Meth” are related mnemonics.

“King Henry Doesn’t Usually Drink Cold Milk” was printed in a 2005 book. “King Henry doesn’t [usually] drink chocolate milk” was posted on freeMATHhelp on July 28, 2006.

“King Henry Died Unexpectedly Drinking Chocolate Milk” was posted on TeacherChat Forums on March 8, 2008. “King Henry Died Unexpectedly Drinking Chocolate Milk. Dumb ass shouldn’t have been so greedy. Mwahahahahahah!” was posted on Twitter by wolfgang8810 on October 21, 2009.

There’s the mnemonic for keeping the basic metric prefixes straight:

. . . . .King Henry doesn’t [usually] drink chocolate milk

...which, of course, stands for:

. . . . .kilo-, hecto-, deka-, [unit], deci-, centi-, milli-

I just nod. To ask him what he’s talking about would mean risking my life.

“That’s how you memorize the basic prefixes in the metric system, dummy,” says Stevie. “Kilo, hecto, deca, units, deci, centi, milli.”

King Henry Died Unexpectedly Drinking Chocolate Milk.  Maybe he was lactose intolerant?  LTHS IED students are using this statement to learn about prefixes with the SI Measurement System.  @PLTWorg @LockportHS205 @PorterPride
