- very easy math question -
**Shreya**, Friday, January 20, 2012 at 8:14pmo never mind i get it. i see i not supposed to multiply by 100 i supposed to divide.

**Kris**, Friday, January 20, 2012 at 8:15pmMilli means 1,000. Centi means 100. There are 1,000 millimeters in a meter, and there are 100 centimeters in a meter. So to go from mm to m, you need to divide .0023 by 1000.

Your answer would then be 2.3*10^-6

I don't know where that 2.3*10^5 came from, did you write it down wrong?

**Shreya**, Friday, January 20, 2012 at 8:22pmMilli means 10 cause there be 10 millimeters in 1 cm. only thing i get wrong be that i times 0.0023mm by 10, i supposed to divide to give me cm. then to get cm into meters i divide by 100 cause there be 100 cm in 1 m. then i get 2.3*10^5.

**Kris**, Friday, January 20, 2012 at 8:33pmActually if you divide .0023 by 10 you get 2.3*10^-4. Then if you divide that by 100 you get 2.3*10^-6.

Dividing .0023 by anything would give you a smaller number, and 2.3*10^5 is a very big number. (230,000)

10mm = 1cm

100cm = 1 m

1m = 1,000mm

1m = 1,000km

**DrBob222**, Friday, January 20, 2012 at 8:40pmmilli does not mean 10. milli means 1000 so there are 1000 mm in a m

0.0023 m = 2.3E-3mm converted to m = 2.3E-6 m

**Shreya**, Friday, January 20, 2012 at 8:45pmok sorry i actually just found that i word it wrong it was not supposed to be 0.0023, it supposed to be 0.023. thanks for helping, i appreciate it :)
