METRIC AWKWARDNESS

Modern metrology has achieved some brilliant coups of measurement but metrologists waste considerable effort coping with the antiquated metric system. The system has meaningless trash numbers for several of its important conversion factors. The latest values can be found on the (National Institute of Standards and Technology) NIST website. The construction of units suggested in the preceding paragraphs results in constants which are often exact and in all cases considerably cleaner.

The metric speed of light is an exact 299792458 meters per second,
compare our exact 10⁹ centipace per trice. Since a mile is 10⁵ cp, this is the same as tenthousand miles per trice. "Milliminute" is a mouthful and I'm trying out "trice" as a substitute name for the time unit.

The metric Planck's h-bar is 1.054 571 596(82) × 10^-34 joule second,
compare our exact figure of 10^-30 erg trice..

The metric Boltzmann's k is 1.380 6503(24) × 10^-23 joule per kelvin,
compare our exact figure of 10^-18 erg per grade.

The metric adopted (1990) exact value for the von Klitzing (quantum Hall) resistance R_H is 25 812.807 conventional (1990) volts per ampere.
Compare our exact 2 pi [voltage unit] per [current unit].

The metric adopted (1990) exact value for Brian Josephson's K_J is 483 597.9 billions of (cycles) per second per conventional (1990) volt.
Compare our angular-format version: 2 × 10¹⁵ per trice per [voltage unit].

The metric gravity constant is 6.673(10) × 10^-11 newton meter² per kilogram².
Compare our 1.000 × 10^-9 dyne centipace² per ounce².

The metric Coulomb's constant is 8.98755... × 10⁹ newton meter² per coulomb². The number is exact but its exact form has too many digits to write out or calculate with conveniently.
Compare our alpha × 10⁹ dyne centipace² per quad², where alpha is the fine structure constant often written as 1/137.
