What Is the BMI? BMI (Body Mass Index) is a standard index first proposed by Adolphe Quetelet in the 1830s. It gives an insight into a person’s physical fitness status. The formula involves Height and Weight. The general expression of BMI is: BMI=Weight/Height2 What Is Z Score?
The science world is filled with different ways to express the vital concept of concentration, which is the amount of something present per unit volume. This "amount" often has units of mass but can include virtually anything that can be quantified: gas particles, photons and more. The volume...
Strain (ε) refers to a ratio of expansion/contraction from the original length and is expressed with formula 1. Unit of Strain There is no unit for strain because it represents an expansion (contraction) as a ratio. In other words, it is treated as a “unitless” number. However, to ...
based on the given response, a respondent can be considered as Promoter, Passive, or Detractor. When they respond to the NPS question, only the numerical value is given, so you need to figure out how many and the percentage of Promoters and Detractors so you can then use the formula to...
To calculate the net burn rate over a set period, find the difference between your starting and ending cash balance, then divide this value by the number of months in this period. The formula looks like this: (Starting balance − Ending balance) / Number of months = Net burn rate For ...
To calculate the break-even point in units use the formula: Break-Even point (units) = Fixed Costs ÷ (Sales price per unit – Variable costs per unit) or in sales dollars using the formula: Break-Even point (sales dollars) = Fixed Costs ÷ Contribution Margin. ...
Mutual fund net asset value (NAV) is a fund's per-share market value. It is calculated by dividing the value of the fund's assets by the number of shares outstanding.
As the nucleon in ~2000 times exceeds electron by mass, mass of the electron bounded in atom is almost negligible compared to the total mass of the atomic core, i.e., the bounded system of nucleus and the rest of atomic electrons. By assuming the nucleus mass infinite the atom is ...
The result is clear. For a 1,000 sq ft room with an 8 ft ceiling and 4 ACH, you need a fan capable of delivering 533 CFM airflow. Let’s use the CFM calculation formula to see if we get the same number (this is the very formula used in the calculator): ...
