The upper side of the ruler is mm and cm. The lower side shows an inch. Also, you can change the graduation of an inch. This option is just below the ruler. There are three graduations that you can choose: 1/8, 1/16, and 1/32. By default, it is selected to 1/16. When you change it to 1/32 then you can see the very small lines appear in between A circle of radius = 0.9 or diameter = 1.8 or area = 2.545 inches has a circumference of 5.655 inches which is equal to: Use the this circumference length calculator above to find the perimeter of a circle given its diameter, or other parameters. What is the area of a circle with a DIAMETER of 12 cm (radius of 6 cm)? How big is a 12 centimeter circle? Diameter cm 2 in 2 ft 2; 12.0 cm: 113.1: 17.53: 0.1217 A centimetre (international spelling) or centimeter (American spelling) (SI symbol cm) is a unit of length in the International System of Units (SI) equal to one hundredth of a metre, centi being the SI prefix for a factor of 1 100. [1] Equivalently, there are 100 centimetres in 1 metre. The centimetre was the base unit of length in the now 3 years ago. Hi, to find the circumference and you have the diameter all you have to do is do the diameter times pi and the answer you get is the circumference. Another formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. 1 cm = 0.39370078740157 in. To convert 3.1 centimeters into inches we have to multiply 3.1 by the conversion factor in order to get the length amount from centimeters to inches. We can also form a simple proportion to calculate the result: 1 cm → 0.39370078740157 in. 3.1 cm → L (in) Solve the above proportion to obtain the length L in inches: KYGh. Like a ship in the empty ocean, astronomers on Earth can turn their telescopes to peer 13.8 billion light-years in every direction, which puts Earth inside of an observable sphere with a radius of How to convert cm to inches. The formula for converting centimeters to inches is: Inches = cm ÷ 2.54 To convert cm to inches, divide your cm figure by 2.54 or multiply it by 0.3937. There are 2.54 cm in 1 inch. Example conversion. Example: Mabel has a step length of 60cm and wants to convert it into inches. She calculates as follows:

how big is 1 cm in diameter
