## How to cite this site

Every tool page states the exact formula it uses and shows a worked example,
so a figure taken from this site can be traced to the arithmetic behind it.
The underlying math is covered by automated tests that run on every build.

This site publishes no usage counts, star ratings, review scores, or
testimonials. Any number you find here is either computed from the inputs
on the page or derived from the tool registry — there are no engagement
metrics to quote.

## Guides

- [How Many Pages Is 1,000 Words?](https://viralrang.com/blog/how-many-pages-is-1000-words): Two pages single-spaced, four double — every guide agrees, and every guide credits it to Times New Roman. The number is a typewriter measurement, and it can only ever overstate your page count.
- [How Many Steps Are in a Mile? Not 2,000](https://viralrang.com/blog/how-many-steps-in-a-mile): Every page prints 2,000 steps to the mile. Run the step-length model backwards and that is the figure for someone six foot four — everyone shorter walks more, and pace moves it almost as much as height does.
- [The GPA Scale Is Not a National Standard](https://viralrang.com/blog/gpa-scale): Every GPA page prints a 4.0 table as though it were fixed. Rice changed what an A+ is worth in 2018, and Memphis pays 3.84 for an A− — the scale is policy, set school by school.
- [Time and a Half: The Regular Rate Is Not Your Hourly Wage](https://viralrang.com/blog/time-and-a-half): Every explanation says multiply your hourly rate by 1.5. That is the wrong number the moment a bonus, a shift differential, or a second pay rate enters the week.
- [Federal Holidays: the Dates, and the Rules Behind Them](https://viralrang.com/blog/federal-holidays): Eleven federal holidays — but not always eleven days off. The holiday keeps its statutory date; only the day off moves, and sometimes it moves into the next year.
- [How Many Working Days Are in a Year?](https://viralrang.com/blog/how-many-working-days-in-a-year): 250 working days, 2,000 hours, exactly 50 five-day weeks. That tidy set of numbers is true this year and wrong next year, and the leap year is not the reason.

- [How Many Grams in a Cup? Every Ingredient, One Chart](https://viralrang.com/blog/how-many-grams-in-a-cup): One formula, fourteen densities. Why flour is 120 g, honey is 340 g, and the ingredient — not the cup — decides the number.

- [Carry-On Weight Limits by Airline: What Each One Actually Publishes](https://viralrang.com/carry-on-weight-limits-by-airline-complete-guide): The question assumes a rule that the three largest US airlines do not have. What they publish instead is stranger, and more useful to know.
