Many aspects of bacterial colonies may be measured for example colony size or appearance can be useful. The measurement which is perhaps the most useful however, is the colony forming units per ml (or cfu) which indicates how many bacterial cells are present to form colonies on the medium. This is a relatively simple calculation which is done by initially counting the number of colonies present on the medium. this number is then multiplied by the inverse of the dilution used. For example, if the dilution of the bacterial broth was 10-2 and the number of colonies on the medium was 60, then the calculation would be 60 x 102. This result is then divided by the volume of sample used in ml and will give you the number of colony forming units per ml present on the medium. Ben McD

Feet per second square ARE the units in this case.
Partial productivity measures are indicators used to analyze activities in terms of a single input (e.g., units produced per worker, units produced per plant, units produced per hour, or units produced per quantity of material).
No. Measurement units are defined by and conversely. So the same units necessarily means same dimensions.

In certain areas of the world the word "into" means "multiply" which is probably meaningful in this case as we are talking about organisms. Hence the meaning is 4 x (10 to the power four) colony forming units per milliliter water and that means 4 x 10000 = 40000 colony forming units per milliliter water.

Total viable count is a method used to estimate the total number of viable bacteria in a sample. This is typically done by plating a diluted sample onto an agar plate and counting the number of colonies that grow. It provides an estimate of the total number of bacteria that are able to grow and reproduce under the specific conditions used in the assay.

Safe levels of total coliform in drinking water are zero colony-forming units (CFU) per 100 milliliters. Any detectable presence of total coliform may indicate potential fecal contamination and further testing is needed to confirm the safety of the water for consumption.

Units produced per hour divided by number of men. example: 15 units produced per hour by 5 men = 15/5 = 3 units per man-hour. If 15 units were produced per hour by only 3 men, the efficiency is better and it will become 15/3 = 5 units per man-hour.
