What does a conversion factor need to equal in the dimensional factor?

You do not want to change the dimension, just how you express the quantity of the dimension (in different units). Therefore, the conversion factor must be dimensionless. So if your dimension is time, for example. A certain amount of time has passed, say 300 seconds. The amount of time is the same, regardless of what units you express it in. 60 seconds = 1 minute. Divide both sides of this 'equation' by (60 seconds) and you have: 1 = (1 minute)/(60 seconds). So if you multiply 300 seconds by [(1 minute)/(60 seconds)], it is the same as multiplying by 1, which is dimensionless. In this example: (300 seconds)*(1 minute)/(60 seconds) = 5 minutes. So, 300 seconds is the same as 5 minutes, and both are expressions of the same amount of time.

How mm convert to pascal?
In order to convert mmHg to kiloPascals, you need to know the conversion factor. Other helpful conversion factor are also listed. Now all you need to know how to do is complete a dimensional analysis problem. 760 mmHg = 101.325 kPa 1 ATM = 101.325 kPa 1 torr = 1 mmHg
How do you find the scale factor of a 2 dimensional figure?
You need information about a pre-image AND and image to work out a scale factor.
Do you need a conversion factor to convert one measurement into another?
Yes, that is true.
How many milliliters are the in 1.8 mg?
There can be no conversion. A milligram is a measure of mass. A millilitre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
What is the conversion factor for cubic centimeters?
You need to specify a second unit to convert to/from. there is now way to just just a conversion for a single variable
How many fluid oz is 80oz?
There can be no conversion. An ounce is a measure of mass. A fluid ounce is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
How many cups is 149 g?
There is no direct conversion. A gram is a measure of mass. A cup is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
How will you change unit of measure for area?
You need to know the conversion factor for the two units you are using.
Two thousand pound is what decimal number?
To convert 2,000 pounds into a decimal number, you need to divide 2,000 by an appropriate conversion factor. The appropriate conversion factor for pounds to a decimal number is 1, as 1 pound is equal to itself. So, to convert 2,000 pounds to a decimal number: Decimal number = 2,000 pounds / 1 pound Decimal number = 2,000 Therefore, 2,000 pounds is equal to the decimal number 2,000.

What is two tenths of an ephah in kilogrammes?
There is no equivalence. A kilogram is a measure of mass. An ephah is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
How many quarts are in one fourth of a ton?
A ton is a measure of mass. A quart is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
