Frequently Asked Questions
What is a unit converter?
A unit converter expresses the same measurement in another unit. It applies a defined factor or scale formula, such as converting centimeters to inches or Celsius to Fahrenheit.
How accurate are Tiny Tiny Tools conversions?
The converters use the unit definitions shown on each page, including exact definitions such as 1 inch = 2.54 centimeters and 1 pound = 0.45359237 kilograms. Displayed results may be rounded for readability.
What is the difference between metric and imperial units?
Metric or SI-based units scale mainly by powers of ten. US customary and imperial systems use units such as inches, feet, pounds, and gallons. US and imperial liquid units are not always the same size, so this site labels them separately.
Why do some results contain decimals?
Different unit systems rarely divide into whole numbers. A decimal preserves useful precision when the converted value falls between whole target units.
Does Tiny Tiny Tools round conversion results?
Calculations retain greater numeric precision, while the interface limits displayed decimal places to keep results readable. Use precision appropriate to the original measurement.
Can I use the converters on a phone?
Yes. The converter fields, unit selectors, tables, and navigation are designed to reflow for smaller screens and remain keyboard accessible.
Do I need to register?
No. The public unit converters do not require an account or sign-in.
