Measuring time

Look:

1 millisecond (ms) = 10^-3 seconds 1/1000 s

1 microsecond (μs) = 10^-6 seconds = 1/1,000,000 s

1 nanosecond (ns) = 10^-9 seconds = 1/1,000,000,000 s

1 picosecond (ps) = 10^-12 seconds = 1/1, 000, 000, 000, 000 s

Note
The symbol used for microsecond is μ s, “μ” is the Greek letter “Mu”
