when one scientist tells another scientist that something
is certain length, that measurement should mean the some thing to both of them.
energy
In a fraction they must be in the same units. In a ratio they need not be.
Measure the depth and width using the same units. Divide the depth measurement by the width measurement.
No. Measurement units are defined by and conversely. So the same units necessarily means same dimensions.
They don't have to have the same value but they have to be in the same measurement units if, for example, you are multiplying the values to find the area of a rectangle.
Because.... There are two types of physical quantities. Fundamental and derived. Fundamental units cannot be derived from any of the two types of units while derived units can be derived from these two types of units. It's important to be clearly defined as there are so many indices of the base number. And no one can derive the units if they aren't properly defined
energy
it is important because it is used to report results and perform calculations. it is used throughout the world to express measurements in metric units
If you wish to compare their respective weights then it is important to use the same units
Units
The same units as the mean itself. If the units of the mean, are, for example miles; then the error units are miles.
Yes, SI units remain the same regardless of where the measurement is taken. The International System of Units is a standardized system used worldwide to ensure consistency and coherence in measurements.
Two measurements are equal when they have the same numerical value, for example 1 inch is equal to 2.54 centimeters. To show equality between measurements, they must have the same units, or be converted to the same units for comparison.
no watt is a measurement of power where as if you meant joule that is a measurement of energy which are not the same thing
In a fraction they must be in the same units. In a ratio they need not be.
The two units are the same measurement.
Yes but the units of measurement are different.
