So, how fast is the speed of light? The speed of light is 299,792,458 m/s in a vacuum. The speed of light in mph is 670,616,629 mph. With this speed, one can go around the globe more than 400,000 times in a minute! One thing to note is that the speed of light slows down when it goes through different mediums. In Scientific Notation. 15 kilometers per hour. = 1.5 x 10 1 kilometers per hour. ≈ 9.32057 x 10 0 miles per hour. Stan Purdum replies: Many beginning road cyclists ride at average speeds between 10 and 14 mph on the road. It's certainly possible to sustain a higher speed, and some new riders who were already runners or some other type of endurance athlete may pedal at 15-18 mph or even higher. Professional bicycle racers can usually maintain 25-28 mph on Convert 1 Cubic Foot Per Minute to Miles/Hour (CFM to mph) with our conversion calculator and conversion tables. To convert 1 CFM to mph use direct conversion formula below. 1 CFM = 0.0010558108348993 mph. You also can convert 1 Cubic Foot Per Minute to other flow units. The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That's about 186,282 miles per second — a universal constant known in equations as "c The g force or g-force, otherwise known as the gravitational force equivalent, is the force experienced by an object with reference to the acceleration to due to gravity value — 9.81 m/s 2 9.81 \text{ m/s}^2 9.81 m/s 2 or 32.17 ft/s 2 32.17\text{ ft/s}^2 32.17 ft/s 2.The force experienced by an object resting on the earth's surface is roughly 1 g 1 g 1 g.Note the g g g is different from the .
