Antique aneroid barometer has a scale of 28 to 31 what units are these?

∙ 16y ago
A meterological type of barometer uses a column of Mercury that is
supported by atmosperic pressure. The height of this column varies
with the atmospheric pressure and was at one time measured off
in inches in the range of about 28 to 31 "inches of mercury".
The scale now used is Millibars both in aneroid and mercury barometers.

What does the pressure units 30.03 in weather mean?
It refers to the atmospheric pressure which, in this case, is measured in inches of mercury on a mercury barometer
What did people use the barometer for?
To measure pressure in the air. Meteorologists use them (weather people) a barometer is used for measuring pressure,the units for measuring pressure include atm,pascal,torr,mm of hg,bars.
What are all the units for the weather instruments?
Degrees Centigrade, centimeters of mercury, and percentages of relative humidity could all be used in a simple weather forecast.
What are the Celsius units called?
Celsius, also known as centigrade, is a scale and unit of measurement for temperature.... The Celsius scale is in general use wherever the metric system of units has been adopted.
How is each step on the pH scale different?
The pH scale is logarithmic; the difference between two units is x10.
What are the units of measurements of an aneroid barometer?
Millibars or inches of mercury are the usual ones.
What two units of air pressure air commonly used in weather reports?
The answer to this question is, the Mercury and aneroid barometer
What two units of air pressure are used commonly in weather reports?
The answer to this question is, the Mercury and aneroid barometer
What type of barometer is the most commonly used today?
The aneroid barometer most commonly used today would be the tiny quartz transducers built into GPS units, sports wrist watches and the like.These would outnumber mercury column types, and other aneroid ones.
What units are used on an antique Danish barometer with a scale of 24.6 t0 29.6?
Just as a guess, they're probably inches of mercury. Standard air pressure is set at 29.92 inches of mercury.
What two units are commonly used to measure air pressure?
Probably a mercury barometer and a aneroid barometer. -adrian
Why is an altimeter important to an airplane pilot?
The altimeter is essentially an aneroid barometer that reads in units of altitude rather than pressure. This is possible by using the standard atmosphere to make the conversion from pressure to altitude.
What is a device for measuring atmostpheric pressure?
The most usual devices are barographs and barometers. A barometer can work off an aneroid cell (eg digital aneroid barometer) or a column of mercury (eg Kew Pattern barometer). Barographs usually work off aneroid cells and through a linkage system print the pressure onto a chart (usually changed weekly although there are daily barometers as well). So the main difference is that a barometer gives a spot reading while the barograph is continuous, although it's possible for the readings from a digital barometer like one connected to an Automatic Weather Station to be saved and called up later, or even printed out in graph form. The usual unit for air pressure in meteorological circles is the hectoPascal (hPa) which replaced the millibar some years ago (the units have the same numerical value, though) except for the US which sticks with the old inches of mercury (InHg).
What are Mercury Barometers and Aneroid Barometers?
A barometer is used to measure air pressure. A Mercury Barometer uses a column of liquid mercury supported by air pressure. The length of this liquid column gives a measure of the air pressure. Air pressure is commonly expressed in terms of "millimetres of mercury" (mmHg). Mercury is considered as a hazardous material and Mercury Barometers cannot be legally manufactured in Europe as of 2007. An Aneroid Barometer traditionally uses an evacuated corrugated metal canister that expands or contracts in response to changes in air pressure and this mechanical movement is amplified to indicate the air pressure in any required units on a calibrated display. The commonest pressure units displayed are in "millibars" (mbar). The latest Aneroid Barometers use a tiny evacuated capsule made of semiconducting materials that responds electrically to changes in air pressure, enabling very precise and repeatable measurement. The electrical signals from this device are processed electronically to provide a visual display of air pressure or to be recorded on a data-logging device as required.
What are the units of a kelvin scale Fahrenheit scale and celsius scale?
The units, in this case, are kelvin, degrees Fahrenheit, and degrees Celsius.
What are the numbers that show the units on a graph called?
scale
What scale is the barometer level measured on?
In the United States, barometric pressure is based on inches - with normal being around 29.9 inches. In other parts of the world, the "SI" or metric units are more commonly used to represent barometric pressure.
