It's about 6,500,000,000,000,000,000 times as fast as Grass growing.
In other words, the speed of Grass growing is 0.00000000000000000015 times 865 times the speed of light.
(for Kentucky Bluegrass, Poa pratensis) (a.k.a. Smooth Meadow grass, a.k.a. Common Meadow grass) (Summer months, ideal growing conditions)
Kentucky Bluegrass, one of the most common grasses in North America, grows about 0.00000000000000014 times the speed of light in the summer months under ideal conditions. When left un-mowed, Kentucky Bluegrass grows to heights of 60 to 90 cm (2 to 3 ft) and blossoms with a blue flower.
It's about 4,000,000,000,000 times as fast as a Sloth.
In other words, 865 times the speed of light is 3,900,000,000,000 times the speed of a Sloth, and the speed of a Sloth is 0.00000000000026 times that amount.
(for Brown-throated three-toed sloth, Bradypus variegatus)
The three-toed sloth moves along the ground at an average speed of 0.00000000022 times the speed of light. Long thought to be lengthy sleepers, a 2008 study concluded that sloths sleep an average of only 9.6 hours per day.
It's about 500,000,000,000 times as fast as an Iceberg.
In other words, the speed of an Iceberg is 0.000000000002 times 865 times the speed of light.
(a.k.a. Berg) (Newfoundland iceberg average)
Moved by ocean currents and wind, icebergs can drift at speeds of about 0.000000002 times the speed of light. The largest iceberg ever recorded was a found near Baffin Island, Nunavut and was estimated to be nine billion metric tons.
It's about 200,000,000,000 times as fast as Walking Pedestrians (in Manhattan).
In other words, the speed of Walking Pedestrians (in Manhattan) is 0.000000000005 times 865 times the speed of light.
(Manhattan; average speed; 8,978 person-sample)
A 2006 Study by the New York City Department of City Planning found that pedestrians in that city walk at an average rate of 0.0000000043 times the speed of light. Pedestrians wearing headphones, the study went on to find, walk at a slightly faster 0.0000000047 times the speed of light
It's about 150,000,000,000 times as fast as Michael Phelps.
In other words, 865 times the speed of light is 133,500,000,000 times the speed of Michael Phelps, and the speed of Michael Phelps is 0.0000000000074906 times that amount.
(at the Beijing Olympics, 2008; 200 m freestyle) (a.k.a. Michael Fred Phelps) (swimmer; 1985-)
Setting a world record, Michael Phelps swam the 200 m freestyle in 1:42.96 for an average speed of 0.0000000064795 times the speed of light. Phelps would go on to win nine gold medals individually in the 2008 Olympics - more than all but eight of the competing nations.
