How you write a millionth as a decimal is always the same, regardless of what unit of measurement it's in. The "1" is six places after the decimal point when writing out one millionth. This is easy to remember because one million in numbers is followed by six zeros. You can also count it out if it helps. The first place is the tens place, then hundredths, then thousandths and it goes up by a factor of ten each time. Ten, hundred, thousand, ten-thousand, hundred-thousand, million! Six places!

.000001 seconds

However, once the issue of units has been brought up it's usually possible to find a shorter way to write it using a smaller (or larger, in other cases) unit of measurement.

1 second = 1,000,000 microseconds

So a millionth of a second is a single microsecond. There are plenty of ways to write a millionth of a second, depending on which unit of measurement you want to use. All of the following are equally correct (though not equally practical), you can pick whichever you'd like.

Q: How do you write one millionth of a second?

Write your answer...

One millionth = 0.00001

One millionth in numbers = 0.000001

No, it is one billionth of a second.

0.000001

One One Millionth

One millionth.

Too short! But a nanosecond is one billionth of a second. --------------------------- Writing one-millionth as an exponent, we have: 10-6 x 10-6 = 10-12 which is one-trillionth. Such a fraction of a second would be a "picosecond." A nanosecond, or one-billionth of a second, is 10-9 seconds.

A millionth is 10-6 or 0.000001; so 4 millionths multiplied together is 10-24 seconds or 0.000000000000000000000001 seconds. (10-6)4 = 10-24 second = 0.000000000000000000000001 second (The 4 millionths are not "multiplied together". One millionth is raised to the fourth power.)

One millionth is 1e-6 or 1 x 10^-6

A millionth is: 0.0001

2,000.000001

One millionth.

A femtosecond is one billionth of one millionth of a second.

one millionth

The prefixes "milli", "micro", and "nano" mean a factor of ten to the power -3, -6, and -9, respectively (or: one thousandth, one millionth, one billionth).

A second! 1 = Ten tenths = Hundred hundredths = Thousand thousandths etc. A millionth of a millionth of a second, or 1/(1million x 1 million) seconds, is called a picosecond. 1/(1 million) seconds, or one millionth of a second, is called a microsecond. 1/(1000 x 1million) seconds, or one thousandth of a microsecond, is called a nanosecond.

A millionth of a second is one microsecond. It is the length of time a beam of light, traveling about 3 x 108 meters per second, will take to go about 300 meters.

1x10-6

2,000.000001

One ten-millionth.

A millionth of the distance that it travels in one second. Take the speed of light, in meters/second or kilometers/second, or even in miles/second, then divide that by a million to get the distance per microsecond.

one millionth , or 10^-6

Two thousand and one millionth = 2,000.000001 Ten thousand and one hundredth = 10,000.01

It is 10 power minus 24 of a second.

1 centisecond (one-hundredth of a second)and for your delectation:-deci - one tenth 1/10centi - one hundredth 1/100milli - one thousandth 1/1,000micro - one millionth 1/1,000,000nano - one thousand millionth 1/1,000,000,000Pico - one million, millionth 1/1,000,000,000,000
