Precision refers to how tightly clustered your data is; accuracy refers to how close that data is to the real value. You might have a dozen miscalibrated thermometers that all tell you the wrong temperature with a very high degree of precision. howtogeek.com/423720/how-…
In 1783, a mysterious admirer of Marie Antoinette ordered her a most complicated pocket watch from Breguet. It included hours, minutes, seconds, perpetual calendar, equation of time, repetition for hours, quarters and minutes, independent seconds, thermometer and power-reserve indicator. breguet.com/en/house-breg…

The Thermoshphere (50 - 450mi above sea level) can reach 4,530 Β°F during the day. Despite this, a thermometer will read below 0 Β°C (32 Β°F) at night, because the the atmosphere is so thin, more energy is lost through radiation than gained through conduction with the "air". en.wikipedia.org/wiki/The…
Thomas Jefferson purchased a thermometer a few days before signing The Declaration of Independence. He noted that it was 76 degrees on Signing Day in Philadelphia. weather.com/holiday/july-…
The Cricket As A Thermometer...Dolbear’s Law states that if you count the number of time a cricket chirps in 15 seconds, and add 40, it will give you (roughly) the temperature in degrees Fahrenheit. en.wikipedia.org/wiki/Dol…
In 1897, a scientist named Amos Dolbear published an article β€œThe Cricket as a Thermometer” that noted the correlation between the ambient temperature and the rate at which crickets chirp. almanac.com/content/predi…
Hood ornaments were originally designed as thermometers for coolant, prior to them becoming decorative en.wikipedia.org/wiki/Hoo…
The Thermosphere is 53 miles above the Earth, and can reach 2,500c, but there are so few atoms to transmit heat that a thermometer might register well below 0c. en.wikipedia.org/wiki/The…
Hood ornaments originally had thermometers to gauge the coolant level in the car. en.wikipedia.org/wiki/Hoo…
When pointed at a mirror, infrared thermometers measure the temperature of the mirror’s surface, rather than the point it’s reflected to blog.thermoworks.com/2017…
William Herschel discovered IR radiation while measuring the temperature of the colors after sunlight passed though a prism. He had a thermometer next to red as the control but saw that it recorded the hottest temperature. en.wikipedia.org/wiki/Wil…
A woman named Jean Hilliard survived a severe 6 hours freezing. She was transported to Hospital where doctors said her skin was too hard to pierce with a hypodermic needle and her body temperature was too low to register on a thermometer. en.wikipedia.org/wiki/Jea…

Trying to quit a play, Jeremy Piven was allowed leave after 'dangerously high levels of mercury' were found in his body. Annoyed, David Mamet said to reporters that Piven was "leaving show business to pursue a career as a thermometer.” theater.nytimes.com/2008/…
The average human body temperature is 98.2 degrees Fahrenheit, not 98.6 degrees. The previous average was calculated with antiquated thermometers in 1868 and was updated using modern technology in 1992. realclearscience.com/blog…
Cars have thermistors rather than thermometers. A thermistor calculates the resistance of electricity as it passes through a sensor. The amount of resistance is determined by temperature. They're accurate, rugged, and cheap. And most importantly they tell us the engine temp and outside temp. en.wikipedia.org/wiki/The…
Alcohol is used in freezer thermometers as it has a lower freezing point than other fluids en.wikipedia.org/wiki/Alc…
The astronauts of Project Mercury, the first human spaceflight program of the United States, flew with a rectal thermometer in them, to record their body temperature during the mission. It was replaced by an oral thermometer on the last of the six manned flights. en.wikipedia.org/wiki/Pro…
The laser on a "laser thermometer" doesn't do anything except help you aim the device. en.wikipedia.org/wiki/Inf…
In 1989, Swiss watchmaker Patek Philippe created "the most complicated watch in the world." Made of 18K gold, the watch has 24 hands, 1,728 components and includes features such as a star chart and thermometer en.wikipedia.org/wiki/Pat…
[] Only a representative of a government weather bureau or similar agency is allowed to bring a mercury weather thermometer or barometer on board an airplane. faa.gov/about/initiatives…
In the first american space flights, astronauts body temperatures were measured with rectal thermometers history.nasa.gov/SP-4213/…

During all but the last Project Mercury flights, throughout the duration of the trip the astronaut's temperature was read and recorded via a rectal thermometer. en.wikipedia.org/wiki/Pro…
If the temperature falls below -37^C, mercury thermometers have to be brought inside to avoid breaking. A Mercury-Thallium thermometer solves this issue. en.wikipedia.org/wiki/Mer…
Breaking a mercury-filled thermometer doesn't cause significant health issues.

I always thought Mercury-based thermometers are an inhouse time-bomb; but if you have one and break it, the health impact is generally minimal. Anyway they are not sold anymore in most countries.

The way a Galileo Glass Thermometer works. The spheres rise as the temperature falls; so of the spheres clustered at the top, the bottom one of those is the actual temp. If the temp rises, the lowest floating sphere will sink, and the new lowest floater is the current temp. 4physics.com/phy_demo/Gal…
There is a tiny pill thermometer that astronauts can swallow to keep track of their stomach's temp. en.wikipedia.org/wiki/Pil…
The infrared ear thermometers are spinoff NASA technology en.wikipedia.org/wiki/NAS…
Most modern thermometers use ethanol, which is the kind of alcohol you drink, and red dye. en.wikipedia.org/wiki/Alc…
