No. Usually there is about a degree difference with the rectal temperature being about 1 degree higher.

Different thermometers make use of different physical properties, that change with temperature - for example, volume, electrical resistance, and others. The basic household thermometer simply has a liquid - previously mercury, nowadays usually colored alcohol - that expands when it is heated.
In terms of accurate, it is assumed the questioner means with respect to core body temperature. Skin temperature is influenced by the ambient (air) temperature, and is therefore not an accurate reflection of the core body temperature. Positioning the thermometer under the tongue yields a close reflection to core body temperature, but this procedure is not always practical, especially with infants and animals. Rectal temperature measures the temperature inside the body cavity, and is therefore a very accurate reflection of the true core body temperature. Furthermore, the rectal temperature can be readily obtained in most cases.
The three types of thermometer are oral, rectal and tympanic. The most reliable is the rectal thermometer.
It's called a rectal thermometer. It gives a slightly more accurate reading than when put under your tongue or in your armpit.

An oral thermometer is designed to be used in the mouth to measure body temperature, while a rectal thermometer is inserted into the rectum for a more accurate reading of core body temperature. Rectal thermometers are typically more accurate but may be less comfortable to use.
Depending on what degrees you are talking about ... A normal thermometer can measure 100 °F - as can an oral or rectal thermometer. A cooking thermometer can measure 100 °C Cryogenic thermometer can measure 100 K. A protractor can measure 100° (depending on the type - they can measure from 0° to 180° or a full 0° to 360°)
The fixed error on a non-digital thermometer is 0.5oC. The percentage error is worked out by dividing 50 by the reading you have taken from the thermometer.

They taste bad!
The tastes differ. An oral thermometer has a longer slender end that's inserted (into the mouth), compared to a rectal thermometer that has a short bulbous end inserted (into the rectum). The bulb reduces the chance of tearing the rectal wall, especially in infants. Some digital models have a setting for rectal vs. oral on the unit. The rectal temperature is known to be a little warmer and more accurate to body temperature. If you still have a glass and Mercury thermometer, be aware that mercury is a deadly toxin, and consider replacing the thermometer with a digital model.
