A measurement can be expressed using a numerical value and a unit of measurement, which together provide a quantifiable description of a physical quantity. For example, length can be expressed as "5 meters" or "3 inches." Additionally, measurements can be represented in various formats, such as fractions or scientific notation, depending on the context and precision required. They may also include significant figures to indicate the accuracy of the measurement.

What are three units of measurment?
Here are some international units of measurement:Mass is expressed in kilograms.Length and distance is expressed in meters.Time is expressed in seconds.Electrical current is expressed in amperes.Speed is expressed in meters/second.
What is the measurement that has been expressed to three significant figure is?
A measurement expressed to three significant figures includes three digits that contribute to its precision, which may include leading zeros but excludes trailing zeros unless they are after a decimal point. For example, the number 0.00456 would be expressed as 4.56 × 10^-3 in three significant figures. Similarly, a measurement like 1500 could be expressed as 1.50 × 10^3 if it is intended to be three significant figures.
What is meant by a mass measurement expressed in this form 4.6 g plus - 0.2 g?
A mass measurement expressed as 4.6 g ± 0.2 g indicates that the measured mass is 4.6 grams, with an uncertainty of 0.2 grams. This means the true mass could range from 4.4 grams to 4.8 grams. The "± 0.2 g" reflects the precision of the measurement, highlighting the potential variation due to factors like instrument limitations or measurement techniques.
