There are two half seconds in a second. This is because a second can be divided into two equal parts, each representing half a second. Each half second would be equivalent to 0.5 seconds.
500 milliseconds is equal to half of a second. 500 milliseconds = 0.5 seconds.
1 minute = 60 seconds 18 x 60 seconds
No, 1 foot per 2 seconds is equivalent to 0.5 feet per second. So, they are not the same.
A nanosecond is one billionth of a second, or 1/1,000,000,000 seconds. Therefore, 9 nanoseconds is nine billionths of a second, or 9/1,000,000,000 seconds, or 9.0 x 10-9 seconds.
1 second = 1,000,000 (one million) microseconds
