In summary, scientific notation is a way to express very large or very small numbers in a concise and standardized way. 2x10-4cm means 2 multiplied by 10 to the power of -4, or 0.0002 centimeters. To convert from centimeters to metres, you need to divide the number of centimeters by 100. Scientific notation is important in measurements because it allows for easier comparison and calculation between different units. However, 2x10-4cm can also be converted to meters without using scientific notation by dividing by 100. The conversion from centimeters to metres is necessary in science because it ensures consistency and accuracy in measurements.

multiply by this conversion factor:

1 = 1m/100cm

it is better for you to familiar with these

cm=10^-2m
mm=10^-3m
um = 10^-6m
nm=10^-9m

It helps you when you calculate...
