[hvswliwv] Cosmological constant as gas mileage

Dark energy induces a small but positive value for the cosmological constant:

lambda = 1.1056e-52 m^-2 = 2.6005e-52 miles per gallon (mpg) = 93.621 micrometer / cubic light year

After consuming a cubic light year of gasoline, your car has traveled only 93 micrometers (3.66 mil) (3.66 thou).

= 3.2483 mm/parsec^3 = 3248.3 km / kpc^3

Can we make sense of dark energy expressed in mpg?

Dark energy, tiny yet pervasive, is the dominant component of the universe, and will become even more dominant over time.
