If using different units of measure in mathematical calculations, you will probably come up with an answer you didn't expect. Different units do not add up. You can not add inches to meters and get something in units of inches or meters. If you want to add quantities together, you need to convert them to the same units. When multiplying or dividing; however, you can do so with different units. For instance, you can multiply newtons (force) by meters (length) and get "newton meters" which is a unit of torque. When doing so just with units of measure, you'd come up with something you might not be able to use very easily. Multiplying a length in feet by a width in meters would yield an area in "foot meters", and I doubt you'd ever use that type of unit.
You would use kilograms (kg) to measure someone's mass in metric units.
I would measure it in maters
Yes
Millimetres
Millimeters.
The mass would not change, only the numbers describing the amount of mass would change.
It depends on what you are measuring the width of. Different units and different tools would be appropriate for a hair, a car or a galaxy.
What measure of units would you use to measure the thickness of a phone book
The metric units used to measure the mass of your weight would be kilograms (kg) or grams (g).
Kilograms.
You would use kilograms (kg) to measure someone's mass in metric units.
The answer depends on the context. There are different things which are measured using different units. For example, flour is measured according to its mass, eggs would be measured in numbers, water, milk or oil by volume. The baker would also need to measure the proving and cooking times and the temperature of the oven.
No. You would use different units of measurement. You would measure the size (circumference) of your waist (for trousers) in centimetres. You would not measure the distance to the moon in centimetres!
I would measure it in maters
There are three different units of measure for temperature, degrees Fahrenheit, degrees Celsius, or Kelvins. (Degrees are not used with Kelvins.)
No solid figure has a surface area equal to its volume. That would not be possible as the units of measure are different.
Yes
