Thread: metric conversion confusion

0.75 kg to mg

0.75 kg x 1000000mg
1kg


i multiplied 1000000x0.75
by hand and came up with the wrong answer don't know what i did wrong
0750000.00

by I know the answer should be 7.5 x 10^5

Please help me understand this

Your result is the same as the given result in scientific notation.

1500 millimeters to km

1500 mm x 1 km
10^6


1.5 x 10^5 is the answer
I am not sure if this is right

where did you get 10 ^3 from

ok now did you subtract the exponents

3-6=-3

why did you make 10^6 to 10^5

Please explain this one too
