Calculators For The Essential Mathematical Terms

Lead time - currently one of the most relevant terms ever which are gaining increasing significance with every passing day. Understanding lead time is the first step to calculating it. Technically lead time is the difference between the initiation and completion of a process. While it is easier to say the number of days a project will take in just numbers, calculating the finite date with the months in different lengths cannot be that easy. This concept is increasingly relevant for shipping and delivery of products for online commerce and other big manufacturers. With the given initiation date and the number of days the process is likely to take, the end date is calculated and given as a delivery estimate for the people concerned. There are many tools available to calculate lead time.

The molar mass of a substance is a physical property. It is the mass of a given substance divided by the amount of the substance. Molar mass is represented by the standard unit kg/mol. But since the calculations are usually at the atomic level, they are represented almost always as ‘g/mol’. This simplifies calculations. The online calculators available at calculate the molar mass of the substances at the atomic level. The calculator gives the output in g/mol for the various elements available and uses the molar mass constant for efficient and dimensionally accurate calculations.

In academics, especially in the practical laboratory experiments, the guide book consists of certain expected values that will come as the result of the experiment. The accepted true value might not always be the answer that actually comes once the experiment is repeated. There are many reasons for this including the change of environment and the difference in equipment. Since scientific experiments usually depend on these factors, the true value cannot be expected every time. There are, however, allowances in the value deviation to a certain extent. These are referred to as percent errors. If the percent errors are not high, and the difference not huge, the values of the experiment are accepted. But even one decimal in the percentage value could change things. This is why it is essential to accurately calculate percent errors. And this can be done using online tools.

We all know perimeter as the length of the path that surrounds a two-dimensional space. Simply put, it can be called the length of the outline of the shape. In a case of a circle or any other continuous differential curve like the ellipse, the perimeter is called circumference. The perimeter of any two-dimensional shape can be calculated easily with the sum of the lengths of its sides. There come many times when we would want to calculate perimeter including for practical applications like fencing a yard and other calculations where it is necessary to note the length of the boundary shape. This is why it is essential to understand the calculations and the formula involved. offers many tools including the ones to calculate perimeter that gives out answers within seconds for the right kind of input.
