Size 1 = 18 inches (approx. 46 cm) in circumference
70 centimeters in circumference is the maximum size of an official soccer ball. The size regulations are : between 68 and 70 centimeters around and weighing between 410 and 450 grams (just under 1 pound).
dunno what is it
On the sides of a soccer ball, you will see a number between 1-5. 1 being the smallest, 5 being the largest and regulation size.
If the ball makes 12 rotations in 10 meters, then 1 rotation takes 83.3 cm. This would equal the circumference of the ball. Then the diameter would be 26.5 cm (or 10.43 inches). This is significantly larger than a regulation soccer ball, which must have a circumference between 68 and 70 cm.
