A standard metric ruler is just slightly longer than 30 centimetres and slightly longer than 12 inches.

The "slightly longer" is for the extra bits of ruler that stick out in front of the 0 (zero) cm/in at the beginning of the ruler and behind the 30 cm/12 in mark at the end of the ruler

The center of gravity on a plastic ruler would typically be located at the midpoint, which is where the ruler balances evenly when placed on a narrow edge or fulcrum. This point is usually at the 15 cm mark on a 30 cm ruler or at the 6 inch mark on a 12 inch ruler.
