Yes.
In the main type the measurement is a ratio of two quantities with the same units so the dimensions cancel out. Nevertheless, the ratio may have a unit. Mach, the ratio of the speed of an object in a medium compared to the speed of sound in that medium. Note that an object travelling at Mach2 in air is travelling much slower than an object at Mach2 in water.
Also, I am not sure how you would treat measurements on arbitrary or subjective scales where there are no explicit units. Examples: Beaufort scale for wind force, or Richter scale for earth tremors. Events are often referred to in the form "an earthquake measuring 6 on the Richter scale", or "winds gusting at 10 or the Beaufort scale".
What else can I help you with?
Can a quantity have unit and still be diamensionless?
No, a quantity cannot have units and still be dimensionless. The dimensions of a quantity are determined by its units, so if a quantity has units, it has dimensions. Dimensionless quantities are those without any units.
Does a dimensionless quantity have a unit?
No, a dimensionless quantity does not have a unit because it represents a pure number without any physical dimension. Examples of dimensionless quantities include ratios, proportions, and mathematical constants.
Which is dimension less quantity?
volume and stress and area have no dimension
Is hours a vector quantity?
No. The Universe is consists of a real dimension and three vector dimensions. The three spatial dimensions are vectors and the one real dimension r = ct includes t the time unit.
What is the dimension of electric potential?
The dimension of electric potential is energy per unit charge, which is equivalent to joules per coulomb or volts. It is a scalar quantity that represents the amount of work needed to move a unit positive charge from a reference point to a specific point in an electric field.
What is dimension of charge?
Electrical charge is a fundamental dimension all by itself, and is not derived fromany other fundamental units. The unit of charge is the Coulomb, which is definedas 1 ampere-second.
What quantity do units represent in a value?
they show the magnitude
What is a defanation of unit?
A unit is a standardized quantity used to measure something. Units are essential for ensuring consistency and accuracy when reporting measurements in various fields such as science, engineering, and mathematics. They provide a common language for expressing the magnitude of a physical quantity.
Weight x distance divided by time?
Weight has same dimension and unit as force. Distance has same dimension and unit as displacement. So weight * distance has same dimension and unit as force * displacement. Force * displacement is work done by the force. Work divided by time to do the work is Power. So weight * distance divided by time also has same dimension and unit as Power although it is not power. S.I. unit of weight * distance divided by time is Newton *meter/second or Nms-1 (in abbr.) It's dimensions are 1, 2, -3 in mass, length and time respectively. Note that given quantity's unit can't be joule/second or watt because weight * distance is not work done, only unit and dimension are same1 . 1. Two physical quantities may have same dimensions and units but that doesn't mean they refer to same quantity.
How does a quantity differ from a unit?
A quantity is a numerical value that represents the amount or measurement of something, while a unit is a standardized amount used to measure that quantity. Quantity is the actual numerical value, while unit is the specific measurement scale used to quantify the quantity.
What are the system defined dimensions in sap bi?
Sap has 3 pre-defined dimensions which are, 1.Data Package Dimension---which will hold the request number 2.Time dimension------will hold values like 0calday, 0calmonth, 3.Unit Dimension-------will hold values for references like currency,units for quantity.
What is meant by unit of physical quantity?
A standard use for a measurement of a physical quantity is called the unit of that physical quantity
