How do you convert measurements to scientific notations?

Answer 1

Move the decimal point so that is immediately to the right of the first non-zero digit and keep track of how many places you had to move it , let's say you moved it e places. If you moved the point to the left , the number in scientific notation is

d.dd... X 10e If you moved it to the right, the number is

d.dd... X 10 -e

Examples

1234.567 = 1.234567 X 103

9010203.98 = 9.01020398 X 106

0.000001234 = 1.234 X 10-6

.0000720 = 7.20 X 10 -5

What about 7.4567? You don't have to move the decimal, so you

moved it 0 places and the answer would be 7.4567 X 100

which is correct but rather silly. You could just leave as 7.4567
