A population survey, better known as a census, entails the collection of each unit in the population. In sample survey information is collected from a subset of the population. The subset, or sample, needs to be selected carefully so that it is representative of the whole population and, if that requirement is met, statistics based on the sample are good estimators for the corresponding population parameters.

The two temperature scales do not have the same unit size. The difference between 80 and 90 ºF is not the same size as between 80 to 90 ºC. Celsius = (Fahrenheit - 32) x 5/9
A meter is a unit of length; a milliliter is a unit of volume.
A square centimeter is a unit of area; a centimeter is a unit of length or distance.
A pica is a unit of type size, a pixel is a unit of illumination.
In a probability sample, each unit has the same probability of being included in the sample. Equivalently, given a sample size, each sample of that size from the population has the same probability of being selected. This is not true for non-probability sampling.
Samplig frame is the source material from which the sample is drawn. If you have a 'list' of names of all inviduals from which you could draw a sample, the list is a sampling frame. A samplig unit is the sample being chosen.

No difference. A unit of stock is called a share.
There is no difference between a unit plan and a scheme of wok. thank u. By highkult
There is no difference.

The key feature is that each sample of the given size has the same probability of being selected as the sample. Equivalently, each unit in the population has the same probability of being included in the sample.

The population consists of every possible unit where a sample is a subset of the population. Note that population and sample need not refer to persons. For example, if studying biodiversity, the population could consist of plots of land.
