There are many different bases for standardisation - even if you only consider the Gaussian (Normal) distribution.
If a variable X has a Gaussian distribution, then the corresponding Standard Normal deviate, Z, is obtained from X by subtracting the mean of X and then dividing the result by the standard deviation of X. The variable, Z, more commonly known as the Z-score, has a Gaussian distribution with mean 0 and standard deviation 1.
But, if X is an IQ score, for example, different measures of the X variable are used so that the resulting variable has mean 100 and standard deviation 15.

What are the reasons for limiting the size of a field in a database?
A reason to limit the amount of data any field contains can vary greatly, but common reason is to standardise the data. One of the principle behind databases is to create collections of data that can be organized into standard format to make it easier to create information for reporting or analysis.

How do you convert CMH to BTU?
CMH is a unit of flow rate (m3/hr or cubic metres per hour) A BTU is a British Thermal Unit, a unit of energy that is equal to around 1055 joules. You cant convert the two as they are a measure of different things, but changing BTU (or Btu) to joules will help standardise the calculations.
