Abstract: A measuring device for calculating the depth of a liquid in a container comprises a dipstick, a plurality of indicia on the dipstick and a thermometer on the elongate member which measures the temperature of the liquid in the container such that the temperature and depth of the liquid is measured. A method of measuring liquid providing an elongate member inserted within a container of liquid such that the elongate member engages a bottom surface of the container. Providing a temperature sensor on the elongate member such that the temperature sensor is submerged in the liquid and reading the temperature of the liquid on a display which displays the temperature sensed by the temperature sensor. Removing the elongate member from the container, locating an imprint from the liquid and reading the level of liquid in the container on a plurality of indicia on the elongate member.
