Answer #1: Joules (J) or Newton metres (Nm)
==================================
Answer #2: Energy
YES!!! For example;- A rectangle may have sides of 3 units and 5 uints. To find the area you multiply these two sides together. Hence Area = 3 units X 5 units = 15 sq. units(square units ) Note the use of the word 'square for area units. Theis method of description is used when measurements are in the Imperial System/ However when using the Metric system, , the units are described as 'Units^2'. Volume becomes 'cu.units' ( cubic units) ; Imperial and 'units^3' ( Metric)
The period of a waveform is measured in units of time, typically seconds (s). In some cases, it may also be expressed in milliseconds (ms), microseconds (μs), or other time-related units, depending on the frequency of the waveform. The period is the duration of one complete cycle of the waveform.
The temperature of a person may be measured in either Celsius or Fahrenheit. Measuring temperature in Fahrenheit is unusual these days, as SI units are normally used.
The measurement of 2.4' refers to 2.4 feet, which is a unit of length in the imperial system. It can be measured using a tape measure, ruler, or any measuring device that is calibrated in feet and inches. In some contexts, it may also be converted to other units, such as meters, for easier understanding in metric systems.
Proportion is typically measured as a ratio or a fraction, representing a part in relation to a whole. It can also be expressed as a percentage, indicating how much of one quantity exists compared to another. In various fields, proportions may be quantified using specific units depending on the context, such as population ratios in demographics or ingredient ratios in cooking.
Uranium is typically measured in units of weight such as grams or kilograms. For radioactive purposes, activity is measured in becquerels (Bq) or curies. In industrial applications, uranium content may also be measured in percentage by weight.
Heat energy is most commonly measured in units of calories or joules.
Both measurements could be correct if they were using different units of measurement. For example, Richard may have measured the chalk in inches while Tanya measured it in centimeters. This would account for the difference in their measurements.
Mass or weight.

The flow rate of a fluid can be measured by techniques such as using a flow meter, which is a device that quantifies the amount of fluid passing through it over a specified time period. Flow rate is typically measured in units such as liters per minute or cubic meters per second.
Petroleum products are typically measured in volume using units such as barrels (bbl) or gallons. For practical purposes, other units like liters or tons may also be used depending on the region and specific product. Measurements are important for trading, transportation, and storage of petroleum products.
A diameter is a line and can be measured in any units of length although some may be more useful units than others. The diameter of a galaxy may be measured in light years, that of a ferris wheel in metres, a car tyre in centimetres, etc. The diameter of a galaxy may be measured in centimetres but you'll simply end up with a very large number.
Elevation can be expressed in units such as feet (ft), meters (m), or miles (mi). It is important to use the appropriate unit based on the specific context or industry in which the elevation is being measured.
The period of a waveform is measured in units of time, typically seconds (s). In some cases, it may also be expressed in milliseconds (ms), microseconds (μs), or other time-related units, depending on the frequency of the waveform. The period is the duration of one complete cycle of the waveform.

It depends a bit on the context. "ms" is basically milliseconds. However, it may also refer to meters/second, which would more properly be written as m/s.
