First you work our how much to divide multiply by ( 1000,100,10 ). Then u add or subtract the amount
There are many conversion tables, both in print and on the internet. Of course,you can only convert units of length to other units of length, - units of weight to other units of weight ,etc.
There are conversion factors. These are available of the web - including wikipedia.
The definition of unit is that it DOESN'T represent anything. For example: two units of water could be two teaspoons or two gallons. The only thing unit-units are used for is comparing.
the unit used to express power is time
"kg/hr" means "kilograms per hour" and "scfm" means "standard cubic feet per minute"Since the units are not compatible, we cant convert to that unit. The time units are consistent, but "kg" and "scf" aren't. "kg" measures mass while "scf" measures volume.Another way to prove this is:"kg/hr" measures mass flow while "scfm" measures volume flow.
For a table comparing the different units of pressure, refer to the related links.
The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.
Speed consists of distance over time. You have to use the same measures of distance and time or the comparison is meaningless. You have to agree on the units in advance, or you have to convert to them.
It depends on what measures you are comparing between!
Baby changing units are very helpful for if you have an infant that needs changing while you are out. These changing units are located in public women's restrooms.
They are 15 and 45 units.
Meter organizes stressed and unstressed sounds into measures.
There is the meter, that measures distance. There is the kilogram, which measures mass. There is the candela, which measures luminous intensity. There is the second, which measures time. There is the mole, which measures amount of substance. There is the Kelvin, which measures temperature. And there is the ampere, which measures electrical current. All other SI units are called Derived Units. Read more in the related link below.
Scales or balances
It depends what you are comparing it with and which units you are using
It measures in volts
Hertz
gret
A rate.
