System of Measurement
In issue 33, Mad published a partial table of the "Potrzebie System of Weights and Measures", developed by 19-year-old Donald E. Knuth, later a famed computer scientist. According to Knuth, the basis of this new revolutionary system is the potrzebie, which equals the thickness of Mad issue 26, or 2.263348517438173216473 mm. A standardization in terms of the wavelength of the red line of the emission spectrum of Cadmium is also given, which if the 1927 definition of the Angstrom is taken for the value of that wavelength, would equal 2.263347539605392 mm.
Volume was measured in ngogn (equal to 1000 cubic potrzebies), mass in blintz (equal to the mass of 1 ngogn of halavah, which is "a form of pie a specific gravity of 3.1416 and a specific heat of .31416"), and time in seven named units (decimal powers of the average earth rotation, equal to 1 "clarke"). The system also features such units as whatmeworry, cowznofski, vreeble, hoo and hah.
According to the "Date" system in Knuth's article, which substitutes a 10-clarke "mingo" for a month and a 100-clarke "cowznofski", for a year, the date of October 29, 2007, is rendered as "To 1, 190 C. M." (for Cowznofsko Madi, or "in the Cowznofski of our MAD." The dates are calculated from October 1, 1952, the date MAD was first published. Dates before this point are referred to (perhaps tongue-in-cheek) as "B.M." ("Before MAD.") The ten "Mingoes" are: Tales (Tal.) Calculated (Cal.) To (To) Drive (Dri.) You (You) Humor (Hum.) In (In) A (A) Jugular (Jug.) Vein (Vei.)
Google's calculator and Wolfram Alpha can perform conversions between potrzebies and other units.

Famous quotes containing the words system of, system and/or measurement:
“You and I ... are convinced of the fact that if our Government in Washington and in a majority of the States should revert to the control of those who frankly put property ahead of human beings instead of working for human beings under a system of government which recognizes property, the nation as a whole would again be in a bad situation.”
—Franklin D. Roosevelt (1882–1945)
“Social and scientific progress are assured, sir, once our great system of postpossession payments is in operation, not the installment plan, no sir, but a system of small postpossession payments that clinch the investment. No possible rational human wish unfulfilled. A man with a salary of fifty dollars a week can start payments on a Rolls-Royce, the Waldorf-Astoria, or a troupe of trained seals if he so desires.”
—John Dos Passos (1896–1970)
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
