50 000 000
It is 50 milliseconds. A decimal representation does not imply a change in the measurement units. If this is required then you need to specify the units into which the quantity is to be converted.
1 second = 1,000 milliseconds. 50 seconds = 50,000 milliseconds
To write 20.5 million numerically, you would write it as 20,500,000.
3,500 milliseconds
1000 milliseconds = 1 second so 50 milliseconds = 50/1000 = 0.05 seconds. Simple!
One billion numerically is: 1,000,000,000
"500 milliseconds", as in the question.
There are 1,000 milliseconds in a second. Thus to convert from milliseconds into seconds you need to divide by 1,000. In this case we have 50,000 milliseconds, so divide 50,000 by 1,000 and we get: 50000/1000 = 50. Thus there are 50 seconds in 50,000 milliseconds.
Ten lakh is written out numerically as 10,00,000.
50 nanoseconds.
1,000,000.
