description:
Per [1] the speed of light in a vaccum is exactly 299792458 m/s.
Per [2] a furlong is 220 yards and a yard is exactly 0.9144 m.
Per [3] a fortnight is 14 days.
As I didn't find a good authority for what definition of a day a fortnight is
measured in, I'll assume here a day is 86400 SI seconds.
Thus, the speed of light in a vaccum is approximately
1.80*10^12 furlongs per fortnight.
1.80*10^12 = 299792458*86400*14/(220*0.9144)

10.0 times 0.1 is hardly ever 1.0.
