the equipment used to make accurate measurements of is a watch
The measurements must be equal to each other.
Yes they must be in the same units of measurements.
A number and a unit
Calibration error and measurement error. Also, if the measurements are of different objects there may be random error.
( 1 ) Measurement should be accurate. ( 2 ) Measurement must have the correct units specified.

The measurements must be equal to each other.
Two measurements are needed - you must find its mass and its volume. Density is mass divided by volume.
Yes they must be in the same units of measurements.
A number and a unit
For two measurements to be a conversion factor, they must represent the same quantity but in different units. The ratio should equal 1 and can be written as a fraction where the units cancel out, allowing you to convert from one unit to another.
To find the density of a sample of matter, you need to measure its mass and volume. Density is calculated by dividing the mass of the sample by its volume.
longitude and latitude
Calibration error and measurement error. Also, if the measurements are of different objects there may be random error.
you can compare two measurements using ratios to find the unit rate.
Their measurements must equal 90° when added together. Supplementary is 180°.
