What fraction of a second is 1 picosecond?
There is a yoctosecond in a MKS (metric system) 1000 yoctoseconds - 1 zeptosecond 1000 zeptoseconds = 1 attosecond 1000 attoseconds = 1 femtosecond 1000 femtoseconds = 1 picosecond 1000 picoseconds = 1 nanosecond 1000 nanoseconds = 1 microsecond 1000 microseconds = 1 millisecond 1000 milliseconds = 1 second 1,000,000,000,000,000 yoctoseconds in a nanosecond
There are exactly 1,000,000,000 picoseconds in a millisecond.
Your question isn't really clear. Speed can't be expressed in just units of distance. It must be a rate, distance per unit time. Such as, miles per hour, or miles per second, miles per picosecond. In an attempt to answer your question though, the speed of light is -- 186,282 miles per second -- 670,615,000 miles per hour -- 16,094,764,800 miles per day -- 5,878,612,800,000 miles per year -- 0.000 000 186 3 mile per picosecond
An attosecond is one quintillionth (10 to the power of minus 18) of a second. As of 2006, the smallest unit of time that was directly measured was on the order of 1 attosecond (10−18 s), or about 1026 Planck times. In physics, the Planck time, (tP), is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length. The unit is named after Max Planck, who was the first to propose it.
There are 100 centimeters in one meter, so the fraction is 1/100

One billion. 1 millisecond = 1/1000th of a second. 1 microsecond = 1/1,000,000 of a second. 1 nanosecond = 1,000,000,000 of a second. 1 picosecond = 1,000,000,000,000. 1000 x 1,000,000,000 = 1 trillion. 1 picosecond is a trillionth of a second.
A picosecond is one-trillionth of a second. It is also one-thousandth of a nanosecond. As such there are 0.000000000001 (or 10-12) seconds in a picosecond.
A picosecond is one trillionth of a second. (10^-12). Or one thousandth of a nanosecond.
