State of constant confusion!

Anyone know how to complete this equation:

35 ns(nanoseconds) = ________ ps(picoseconds)

The following is a list of how many units are in a second:

1,000 millisecond = 1 second
1,000,000 microseconds = 1 second
1,000,000,000 nanoseconds = 1 second
1,000,000,000,000 picoseconds = 1 second

If you know the answer, PLEASE, elaborate on how you figured it. I am having trouble grasping how to calculate these types of problems and that is a rarity for me. I'm usually very good at math.

Thanks!

well an easy way to do it is:
divide the ps units by the ns units to get 1000..so you will see that
a picosecond is 1000 nanoseconds.

so if you have 35 ns then if you mulitply by 1000, you get 35000 ps.

as you see in the unit conversions youve given
second x 1000 = millisecond
milisecond x 1000= microsecond
microsecond x 1000= nanosecond
nanosecond x 1000 = picosecond

so..
you know by multiplying by that thousand you are moving your decimal place over
to the right by 3 places ...

does this help any?

See? I knew the answer would be something simple.

Thanks muted I appreciate that

Relate each to each, Jeffery, instead of all to a second, and it makes better sense. All you need to do at each step in the process is multiply by a thousand.

8) 1000 yoctoseconds = 1 zeptosecond
7) 1000 zeptoseconds = 1 attosecond
6) 1000 attoseconds = 1 femtosecond
5) 1000 femtoseconds = 1 picosecond
4) 1000 picoseconds = 1 nanosecond
3) 1000 nanoseconds = 1 microsecond
2) 1000 microseconds = 1 millisecond
1) 1000 milliseconds = 1 second

Since you want to move up the ladder, from nanoseconds to picoseconds, you're going to multiply by a factor of 1000. How many times you multiply by 1000 is determined by how many steps between the levels. Level 4 (pico) - Level 3 (nano) is obviously just 1 level, so 35 nanoseconds is equal to (1 * 1000 * 35) picoseconds.

Ron... If you can come up with all of those, then I think you just might have a bit too much time on your hands.

oh goodness LOL, Ron's working with numbers i hope to never see! LOL
then again, some amazingly tiny things in electron microscopes...may yet be using those tiny units

teamwork always wins

Holy cow! Ron, I hope I never, ever have to work on numbers that big LOL

Thanks though, that makes it much easier

Btw, why is it important to convert from one time unit to another? Guesses anyone?

But.. But... It's really not BIG numbers we're dealing with here - It's teeny tiny numbers.  These are all fractional parts of seconds we're talking about...

Such as:

8) 1 yoctosecond = 0.000000000000000000000001 of a second - or - 0.1 x 10(-23 exponent)
7) 1 zeptosecond = 0.000000000000000000001 of a second - or - 0.1 x 10(-20 exponent)
6) 1 attosecond = 0.000000000000000001 of a second - or - 0.1 x 10(-17 exponent)
5) 1 femtosecond = 0.000000000000001 of a second - or - 0.1 x 10(-14 exponent)
4) 1 picosecond = 0.000000000001 of a second - or - 0.1 x 10(-11 exponent)
3) 1 nanosecond = 0.000000001 of a second - or 0.1 x 10(-8 exponent)
2) 1 microsecond = 0.000001 of a second - or - 0.1 x 10(-5 exponent)
1) 1 millisecond = 0.001 of a second - or 0.1 x 10(-2 exponent)

Geesh...

well, i dont know why you need to convert to such small time units, but i know why i need to convert to such small length measurements... i get the glorious task of measuring the Ribosomes in cells (various types) LOL
talk about tiny!!

maybe you learn such small measurements of time because i suppose dealing with how fast maybe the brain submits signals, or how fast a computer processes information, and in alot of cases how quickly a very unstable isotope breaks down

what do you study by the way?? LOL

All it is 35*1000. Then you add in the corresponding 0's.
