This April Fools’ post was supplied by Peter Goodyear, a staunch help to yours truly, Reddit metric system moderator and Australian supporter of our leaving our foolish measurement ways behind us. LA
Some Americans are concerned that their measurement system (still in use from when America was a collection of British colonies,) is unnecessarily complicated. They argue that it is difficult to learn and to use, and in these modern times it is difficult to programme into computer applications. (It is also used only by Americans, however this is seen as an expression of American Exceptionalism™ and is therefore not regarded as a disadvantage.)
Radically progressive Americans believe that adopting the French, or metric, system of measurements would solve the problems caused by learning and using measurements inherited from Colonial times. Opposing them, American Traditionalists claim that what was good enough for their forefathers is obviously good enough for everyone today.
No American since Thomas Jefferson has proposed a logical and simple system of measurements, thus the available choices are either to retain a British system which is slowly being abandoned, even by the British themselves, or to adopt a French system which has, in recent years, gained a modicum of acceptance in several corners of the globe.
To satisfy both American Traditionalists, who want to retain long-established British weights and measures, and Metric Radicals who want them swept away and replaced with SI† metric units, I propose a compromise: the centimetre-gram-second system.*
The centimeter-gramme-second system (cgs) combines the least advantageous features of both metric and US Customary measures, so both sides will have an equality of dissatisfaction with its introduction.
(*As this is a British measurement system I will use the British, or proper, spelling of “meter”, to wit: ’metre’.)
The features of the CGS system:
1) It’s metric. Obviously.
The centimetre-gram-second system is obviously based on metric units, the centimeter, the gramme and the second. Supporters of traditional units will claim that this is a massive strike against it, but this is balanced by several other features which will be welcomed by American supporters of traditional British units, namely:
B) It’s a traditional British system.
Cgs was developed by the British Association for the Advancement of Science (usually abbreviated to BA,) and introduced in 1874. Undeniably British.
At more than 140 years old, it’s older than a lot of American traditions such as the Super Bowl, (first Super Bowl was in 1967,) Veterans Day, (started11/11/19, American style, or 11/11/19 in the world-wide dating system,) the Oscars (first awarded in 1929) or Mother’s Day (dating from Mother’s Day 1914).
iii) It’s difficult to use.
Conversion factors between cgs and SI units are awkward because there are 100 centimetres in a meter and 1000 grams in a kilogramme, which promises the possibility of introducing order-of-magnitude errors everywhere. In addition, there are odd conversion factors between some of the units in the electrostatic, electrodynamic and Gaussian systems of CGS. (Didn’t I mention that there are three different systems of cgs? I know you Americans just love to have a choice!)
Whilst the CGS system is useful for fine measurements such as one finds in atomic physics or engineering, it is difficult to use with the extremely large order-of-magnitude quantities encountered in engineering or astrophysics.
Fifthly) Nobody else uses it.
The BIPM‡ recommended using the SI system, a refinement of the Metre-Kilogram-Second system, in 1960, and since then SI has supplanted the cgs. This allows for the perpetuation of American Exceptionalism™ in employing a measurement system no-one else uses, or would want to use.
Bonus: In addition to the CGS units there is an obsolete BA metric screw thread which could be introduced (with some inconvenience, no doubt,) to replace SAE fasteners.
I am confident that both metric advocates and adherents of US traditional standards will have equal measures of support for this proposition. Your comments are welcome and I will give them the attention they deserve.
Stop Press: Last-minute research has shown that cgs units are still used in the astronomical sciences. This will no doubt make CGS adoption easier due to the massive influence that astronomy has in everyday life through astrology, the calendar, tides, etc.

I propose a different angle. Remove any legal status from imperial and USC. Allow all of the unit names to be recycled as exact values of a rounded metric dimension. 1 ounce = 30 mL & 30 g; 1 inch = 25 mm; the mile would be 1600 m even if it doesn’t work out nicely in feet or inches. The pound would have to be decided if it is to be an exact 500 g or 480 g based on 16 x 30.
Keep the names for those that want them and the measurements will always be dome metric.
