The process of comparing an unknown quantity to a standard known quantity is called calibration. This involves measuring the unknown quantity using a calibrated instrument or reference standard to determine its accuracy and reliability. Calibration ensures that measurements are consistent and accurate across different devices or instruments.
To compare an unknown quantity with a standard means to evaluate the unknown by measuring or examining it against a known or established reference point. This process helps to determine the value or characteristics of the unknown quantity in relation to the standard.
A comparison between an unknown quantity and a standard is known formally as a measurement. In essence, by taking a measurement of a standard against an unknown quantity, you are creating your own system of measurement.
In the external standard method for X-ray diffraction (XRD) technique, a known standard sample is used to calibrate the XRD instrument before analyzing unknown samples. The intensity of characteristic peaks from the standard sample is measured and used to calculate the correction factor or calibration curve, which is then applied to quantify the phases in the unknown samples based on their XRD patterns.
Beam balance measure mass by comparing unknown quantity with known standard quantity of mass.Beam balance measure accurate quantity of matter present in that body .Quantity measured by beam balance doesn't differ in any place of world either in poles or equator but measuring scale quantity differ in different places
Yes, you can compare a known quantity with an unknown quantity in making measurements by using the known quantity as a reference point to determine the value of the unknown quantity. This comparison can help provide a basis for estimation or calculation in determining the value of the unknown quantity.
dear friend, simply measurement means the comparison of any unknown quantity with a known quantity.for ex, when we measure rice using a balance.we usually put one standard quantity in one pane while we put the unknown quantity in another pane.so, isn't this a comparison

The red, blue, and yellow paints are used as reference standard colors for comparison with the unknown paint sample after chromatography. By comparing the colors from the unknown sample to the standard colors, it helps in identifying the components present in the unknown sample based on their chromatographic separation pattern.
In maths the symbols x and n are usually used to represent an unknown quantity. These may be referred to as a variable.
