Anyone come up with a good measure of distance that makes the speed of light a nice round number? I like the metric system, but the meter feels pretty arbitrary. We could do better!
In radio electronics we abbreviate c to 300 000km/s (when working in kHz, different multipliers in other bands for easy maths). The number as it is is round enough when rounded to the whole hundred million for practical purposes with commodity hardware
We could redefine the metre to be 1.00069229…x it’s current size (increase it by 0.69229…mm) to make the speed of light exactly 300 000 000ms-1. This would also change area and volume, and any other units that are derived from length
