Convert 1 foot 6 inches to centimeters

1'6" = 45.72 cm

A foot is exactly 30.48 cm and an inch exactly 2.54 cm, so multiply each part and add them up: 1 foot 6 inches = 45.72 cm.

Divide by 2.54 to get the total inches, then divide that by 12: the whole part is the feet and the remainder is the inches. That takes 45.72 cm back to 1 foot 6 inches.

Exact. The inch has been defined as exactly 2.54 cm since the 1959 international yard and pound agreement, and a foot as twelve of them, so converting 1 foot 6 inches introduces no approximation.
