The temperature will differ depending the size of moxa cones. Generally, an extremely small cone is as thin as a thread. A small cone is about 2 ~ 5mm in diameter and 4 ~ 8mm in height. A medium cone is about 6 ~ 10mm in diameter and 9 ~ 13mm in height. A large cone is about 11 ~ 15mm in diameter and 14 ~ 25mm in height. See Figure D1 for the common sizes of moxa cones.
