The principle is the proportional dilatation of mercury with temperature.
Anders Celsius, a Swedish astronomer, invented the Celsius thermometer in the 18th century.
Swedish scientist Anders Celsius invented the Celsius scale of temperature. The first thermometer was invented by Galileo Galilei..but he most certainly wasn't Swedish.
Gabriel Fahrenheit was the inventor of Thermometer and not a Swedish but a German.answ2. the Swedish scientist asked about was Anders Celsius, after whom the Celsius temperature scale is known.Other contenders for thermometric fame were Rankine, Reaumur, and Romer.And of course William Thomson, more commonly known as Lord Kelvin.
The first modern thermometer was invented by Galileo in the early 17th century. The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in the early 18th century. The Celsius scale was developed in the mid-18th century by Anders Celsius.
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
Anders Celsius
Yes, he did.
The Celsius scale is from 1742.

Anders Celsius invented the temperature scale that bears his name.
The temperature scale that bears his name.
Anders Celsius, a Swedish astronomer, created his temperature scale in 1742.
He chose water because it is world's most common liquid to test.
Anders Celsius
because his parents died so he went to work at a store then he was interested in scientific instrument and then he made his own instrument called the thermometer and he named it after himself Fahrenheit then alittle bit after anders celsius made celsius which we use in America now to tell wheather.
