what is 9cm=______in

do I have to mutiply by 2.54 which equals 22.86,is i'm right or wrong?

1 inch is a longer unit of measurement than 1 cm

so 9 cm = 9/2.54 inches = 3.54 inches

look at your ruler (most have both units on them) and see how long 9 inches are.
Now how long would 22.86 inches be?

look at the 3.5 mark for inches, isn't that at about the 9 cm mark?

yes I see, thank you i really got confused at one point ,but i think i had 3.54 inches before but i didn't know if i was right about it either, thanks for your help:)

To convert centimeters to inches, you need to divide the length in centimeters by the conversion factor, which is 2.54. So, let's calculate 9 cm in inches:

9 cm ÷ 2.54 = 3.5433070866 inches (rounded to the nearest tenth)

Therefore, 9 centimeters is approximately equal to 3.5 inches, not 22.86 inches. It seems like you made an error in your calculation. Remember, to convert cm to inches, you divide by 2.54, not multiply.
