What is an anthropometric measurement?
The term anthropometric refers to comparative measurements of the body. Anthropometric measurements are used in nutritional assessments. Those that are used to assess growth and development in infants, children, and adolescents include length, height, weight, weight-for-length, and head circumference (length is used in infants and toddlers, rather than height, because they are unable to stand). Individual measurements are usually compared to reference standards on a growth chart.
What is a vector measurement?
A measurement that has magnitude and direction. The magnitude is equal to the absolute value of the vector measurement. For example, Velocity is a vector measurement. A velocity of -20 miles per 1 second would suggest moving away from the origin point in a two-dimensional measurement at a rate of 20 miles per 1 second. The absolute value of this would be 20 miles per 1 second, which would also be the speed. Therefore, speed is the magnitude of Velocity. Subsequently, any measurement that has a magnitude, but no direction, is not a Vector measurement, but rather a scalar measurement. Some examples of vector measurements would be Displacement, Velocity, and Acceleration.
What does customary mean in math?
using classical rather than metric units of measurement
What is an example of quantitative measurement?
data or information that is measured numerically rather than qualitatively.
What a the measurement of a king duvet?
When the term "king size" is used it refers to the Eastern king mattress rather than the California king. An Eastern king mattress measures 80" by 76". The average size quilt/blanket/duvet for the Eastern king is 90" by 108".
Why do measurements have to be standard?
Standard measurements are rather like the standard meanings of the words that you and I are using to communicate with each other. If a word has a standard meaning, then when I use that word you will know what I mean. If I use a standard measurement, then I can tell other people what I have measured and they will know what the measurement means.
What measurements or observations tell that a car is accelerating?
Frame of reference is the measurement or observation that tells you that a car is accelerating. It uses the second law of motion to tell you rather or not the car is accelerating.
What is the precise measurement of a mailbox?
Mailboxes do not have precise measurements, as they are not produced by the government, in the US, anyway; rather the US Mail sets parameters, max and min measurements, within which post boxes may be produced by the commercial sector. For the correct parameters for a US Mail box, go to mail.gov.

What is the measure the capacity of caton of cream?
Cream comes in several sized cartons. You can get a cup of cream, a pint of cream, or a quart of cream. These are measurements of volume rather than mass, since liquids are measured by volume.
What is indirect volume?
Indirect volume refers to the process of estimating the volume of an object indirectly, often through calculations based on other measurements or data rather than directly measuring the volume itself. This method is commonly used when direct measurement is not feasible or accurate.
What is the definition and example of direct measurement?
direct measurement is when you get the answer to your data straight from the experiment rather than calculating numbers in order to receive your answer in the end.
How the method of establishing the scientific length of meter has change over the last 200 year?
It comprises a system of units of measurement devised around seven base units and the convenience of the number ten. The SI was established in 1960,[3] based on the metre-kilogram-second system, rather than the centimetre-gram-second system, which, in turn, had several variants. The SI has been declared to be an evolving system; thus prefixes and units are created and unit definitions are modified through international agreement as the technology of measurement progresses, and as the precision of measurements improves. measures
What is the definition of standard system of measurement?
A measurement standard is an agreed upon comparison for people to trade or make measurements. The International System of Units has defined the agreed standards for measurements. Modern standards are based on non arbitrary standards when possible for example time (seconds) is based on the oscillations of a cesium-133 atom; length(metres) is based on the distance that light travels in a vacuum in 1⁄299,792,458; weight(kg) is still measured by an artefact rather than an agreed physical property. Previously/historically the agreed standards could be whatever the ruler/merchants decided upon in that area.
