There are 7,000 millimetres in 7 metres... and you have one too many zeros in you question !
.00001 (or 1 x 10-5) hectometers are in 1 millimeter
There are .00001 mm in 1 km.
.00001 x 3 = .00003
point 00001 as a percent = 0.001%0.00001 * 100% = 0.001%
1 centimeter = .01 meter 1 kilometer = 1000 meters 1 centimeter = .00001 km x13 = .00013km
One inch = 25,400 microns; so .00001 inch = 0.25400 microns
.00006
1 meter= 100 centimeter 1000 meters= 1 kilometer so 1 km/(1000 m*100 cm)= .00001 km in a cm
.00001
There is none.
243.84 Meters squared, Remeber you can always type these conversion questions into http://www.google.com and it will convert it for you to the nearest .00001 so that's something to think about
100,000.
