How do you describe numerical value?
A numerical value is a quantitative representation of a specific amount or measurement, expressed using numbers. It can denote whole numbers, fractions, or decimals and is often used to convey data in mathematics, science, finance, and everyday life. Numerical values can also signify rankings, scores, or quantities, providing a basis for comparison and analysis.
Why do fractions and decimals exist?
Fractions and decimals exist to represent parts of whole numbers, allowing for a more precise expression of quantities that aren't whole. They enable the division of units into smaller segments, facilitating calculations in various fields such as mathematics, science, and finance. By using fractions and decimals, we can convey values that improve accuracy in measurement and comparison, enhancing our understanding of relationships between quantities.
What do you understand by the term of measurement?
Measurement refers to the process of quantifying physical quantities or characteristics using established units and tools. It enables comparison, analysis, and understanding of various attributes, such as length, weight, volume, and temperature. Accurate measurement is essential in fields like science, engineering, and commerce, as it provides a basis for decision-making and ensures consistency in results.
Why quantity do units represent in a value?
Units represent quantities by providing a standardized measurement that conveys the amount of a specific attribute, such as length, weight, or volume. For example, meters measure distance, while kilograms measure mass. By using units, we can communicate and compare quantities effectively, allowing for clear understanding and analysis in various fields such as science, engineering, and everyday life. Ultimately, units help translate abstract numbers into meaningful information that can be universally understood.

What is the math definition of !?
math: the science dealing with quantities forms etc. and their relationships by the use of numbers and symbols As defined by Dictionary.reference.com : Mathematics is the systematic treatment of magnitude, relationships between figures and forms, and relations between quantities expressed symbolically.
What is the difference between metrology and measurement?
Metrology, as defined, is the science of measurement. However, in practice, metrology is a term applied only to the science behind measurements of length and angles, the basic quantities of space measurements. All other quantities (temperature, stress, pressure, weight, time, etc) are not included in the everyday use of metrology. Measurement, on the other hand, is the application of metrological principles for determining verious lengths, angles as also of quantities like weight, time, etc. While metrology deals with thoretical aspects only (being the science), measurement deals with application of the principles for making the instruments and devices for measuring the quantities and cmparing them with standards.
What is the cornerstone concept in physics?
Experiment. Experiments involving measurement of the number of multiples of the base units in each of the ways reality can be measured. That is why physics is called the quantitative science, the science of quantities where a quantity is a numerical value multiplied by units of measurement.
What is the purpose of measurement in science?
The purpose of measurement in science is to quantify and describe physical quantities and properties. It allows for comparison, accuracy, and repeatability of observations and experiments. Measurements provide a common language for scientists to communicate their findings and draw conclusions based on data.
What is metrology the science of?
Metrology is the science of measurement. It involves the study of measurement techniques, standards, and systems used to quantify physical quantities such as length, mass, time, and temperature with precision and accuracy. Metrology is crucial in various fields such as industry, research, and technology to ensure consistency and reliability in measurements.

What is the definition of a metric system and how is it used in the field of science and measurement?
The metric system is a system of measurement based on the meter, kilogram, and second as fundamental units. It is used in science and measurement to provide a standardized and consistent way to quantify and compare physical quantities. Scientists use the metric system because it is easy to convert between units and promotes international collaboration and communication.

Explain that science is based on physical quantities?
Science is totally based on physics because this subject (Physics) has a very deep root in each and every aspect and branch of science . for example: If we talk about Biology. Whenever a doctor operates a human body he needs to have at-least the basic ideas of the Laws, Rules and Principles of Physics. Specially when he has to operate The functions of lever, he has to work with some common principles of Physics, or motion.
How do you explain about science and technologies?

What are Physical quantities?
They are properties that you can measure and be verified by another party. Usually, standards are available to eliminate any difference in measurement methods and definitions. For example, we can measure length, speed, weight, humidity, temperature, and time, with certainty. Those are physical quantities. Contrarily, we cannot measure inflation rate, hunger, pain, etc. with certainty. In short they are quantities that can be measured.
Is math science?
Math is not considered a science in the traditional sense, but it is closely related to science and is often used as a tool in scientific research and analysis. Math is a discipline that deals with numbers, quantities, shapes, and patterns, while science is a broader field that encompasses the study of the natural world and the processes that govern it.
