How can I convert mm to cm and cm to mm
Look at the metric system, a part of which is shown below. The prefixes are
kilo
hecto
deka
unit--grams, liters, meters, etc.
deci
centi
milli
Stearting anywhere on the scale of prefixes above, count the number of places to get from where you are to where you want to go and move the decimal point to the left if you move up the chart and move the decimal point to th right if you go down the chart.
For 10 mm to cm. Start at millimeters (mm) and move 1 space to get to centimeters. So move the decimal 1 place to the left and 10 mm = 1.0 cm.
convert 10 kg to centigrams. Start at kilo, and count 1 to hecto, 2 to deka, 3 to the unit (in this case the gram), 4 to deci and 5 to centi. Move the decimal point 5 places to the right and 10 kg = 1,000,000 cg.
To convert millimeters (mm) to centimeters (cm), you need to move the decimal point one place to the left. So, for example, if you have 10 mm, you would move the decimal point one place to the left and get 1.0 cm.
To convert centimeters (cm) to millimeters (mm), you need to move the decimal point one place to the right. So, for example, if you have 1.0 cm, you would move the decimal point one place to the right and get 10 mm.
This conversion is based on the metric system, where prefixes indicate the magnitude of the unit. Starting from the unit (in this case, the gram, liter, or meter), you count the number of places to get from one prefix to another. Moving up the chart (e.g., from mm to cm) requires moving the decimal point to the left, and moving down the chart (e.g., from cm to mm) requires moving the decimal point to the right.
I hope this explanation helps you understand how to convert between mm and cm!
