Closest first | Highest first | Lowest first

 It's about 40,000 times as fast as a Sloth In other words, 10,000 kilometers per hour is 41,000 times the speed of a Sloth, and the speed of a Sloth is 0.0000240 times that amount. (for Brown-throated three-toed sloth, Bradypus variegatus)The three-toed sloth moves along the ground at an average speed of 0.24 kph. 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 one-one-hundred-thousandth as fast as The Speed of Light In other words, 10,000 kilometers per hour is 0.00000926566931105980 times the speed of The Speed of Light, and the speed of The Speed of Light is 107,925.284880 times that amount. (C) (in a vacuum)The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures 1,079,252,848.80 kilometers per hour, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 719,501,899.2120 kilometers per hour when passing through the glass of a typical window. It's about 70,000,000,000 times as fast as Grass growing In other words, 10,000 kilometers per hour is 69,000,000,000 times the speed of Grass growing, and the speed of Grass growing is 0.0000000000140 times that amount. (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 0.000000150 kilometers per hour 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.
