The reading time calculator takes daily reading time, average reading speed and total reading time and returns period spent reading, book’s length and daily reading. It is built for quick answers, for checking somebody else’s arithmetic, and for the moments when a formula book is not within reach.
What Is the Reading Time Calculator?
The reading time calculator turns daily reading time, average reading speed and total reading time into period spent reading, book's length and daily reading.
It is a quick way to get from the numbers you have to the number you need, without setting up a spreadsheet or reaching for a formula.
How the Reading Time Works
Each result follows from the ones before it, and the calculator shows every step, so a surprising answer can be traced back to the input that caused it.
Round your inputs to the precision you actually know, and keep more precision than that in the intermediate steps.
Getting a Result You Can Trust
Run the calculation twice with slightly different inputs. A sensible calculator moves its output in proportion; a wild change points to a unit or a decimal point problem in what you entered.
Write the inputs down next to the answer. It takes a moment and it is the difference between a number you can explain and one you cannot.
A Worked Example
Working through an example, with daily reading time set to 10, average reading speed set to 5, total reading time set to 2, the calculator returns book's length of 10, and period spent reading of 0.2, and daily reading of 50. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out period spent reading?
Enter daily reading time, average reading speed and total reading time. The calculator then works through the relationship and reports period spent reading, book's length and daily reading.
What does the reading time actually calculate?
It takes daily reading time, average reading speed and total reading time and converts them into period spent reading, book's length and daily reading using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter daily reading time?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
