∙ 12y agoTake a piece of string. Wrap it around your finger, being sure that it neither too tight to bind and that you can slide it over your knuckle without difficulty, nor so loose that it will slip over your knuckle almost by itself and thus easily fall off. when you have found this comfort zone, mark the string where the ends cross and then measure the length of this piece in mm. An on-line reference or a jeweler can then tell you what ring size this measurement corresponds to.

A good way to measure dissolved oxygen levels in the human body would be to use a pulse oximeter. It is a little device that you can put on a finger or toe to get the measurement.
Oxygen levels in the blood are typically measured using a device called a pulse oximeter. This device clips onto a person's finger and uses light to measure the level of oxygen saturation in the blood. The reading is expressed as a percentage, with normal levels typically ranging from 95-100%.

Most modern oximeters have a built in pulse reader. Your finger is placed in the oximeter, also measuring your pulse along with the % of O2 in your blood.
