a) How many milliseconds (ms) are in 1 second?

1 second = 1000 milliseconds

1 second = 10^3 milliseconds

b) How many microseconds (μs) are in 1 second?

1 second = 1000000 microseconds

1 second =  10^6 microseconds

c) How many nanoseconds (ns) are in 1 millisecond?

1 millisecond = 1000000 nanoseconds

1 millisecond =  10^6 nanoseconds

d) How many microseconds are in 1 millisecond?

1 millisecond = 1000 microseconds

1 millisecond =  10^3 microseconds

e) How many nanoseconds are in 1 microsecond?

1 microsecond = 1000 nanoseconds

1 microsecond = 10^3 nanoseconds

f) How many kilobytes (KB) are in 1 gigabyte (GB)?

1 gigabyte = 1000000 kilobytes

1 gigabyte = 1000 megabytes

1 gigabyte = 10^3 megabytes

i) How many bytes are in 20 megabytes?

1 megabytes = 1000000 bytes

20 megabytes = 20000000 bytes

20 megabytes = 2\times 10^7 bytes
