Calibration is a comparison between measurements - one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device.
The device with the known or assigned correctness is called the standard. The second device is the unit under test, test instrument, or any of several other names for the device being calibrated.

The process designed to ensure accuracy of measurements through routine operations is called calibration. Calibration involves comparing measurements from a device to a known standard and making adjustments if needed to correct any errors in the measurement instrument.
The accuracy of a measurement is influenced by factors such as equipment precision, calibration, environmental conditions, human error, and the skill and experience of the observer. Consistency in measurement techniques and proper instrument handling also play a role in determining measurement accuracy.
There is no difference between degree Celsius and Celsius degree. Both terms are used interchangeably to refer to a unit of temperature measurement on the Celsius scale.
The most important part about measurement is accuracy. It is crucial to ensure that measurements are precise and consistent to obtain reliable data and make informed decisions. Calibration and proper units of measurement are also important considerations in the process.
Accuracy is a measure of how close to an absolute standard a measurement is made, while precision is a measure of the resolution of the measurement. Accuracy is calibration, and inaccuracy is systematic error. Precision, again, is resolution, and is a source of random error.
Calibration is the validation of specific measurement techniques and equipment.

An actual measurement is going to be more accurate than an estimate.
To check the precision of an instrument its apparent measurement must be compared to a known measurement. The difference between the measured quantity divided by the known quantity is expressed as a % precision of the instrument, or calibration. Most instruments when being calibrated are tested against multiple known quantities throughout the range of the instrument. Thus the precision of the instrument is determined throughout it's full range of measurement.
i dont know.hahahah..

Subtract the least measurement from the greatest one. That will give you the difference. If you're talking about a set of numbers, that's known as the range.
After maintenance, one must often replace and re-calibrates meters and gauges. The right time interval between these calibrations varies relying on the user’s experience with the meter and thus the importance of the measurement.
Calibration error and measurement error. Also, if the measurements are of different objects there may be random error.
The difference between fiscal & non-fiscal metering is when the measurement value is relevance to money.
