How to use Unit Converter
- 1
Choose length, weight, or temperature.
- 2
Enter a value and select the source and target units.
- 3
Read the converted value.
Conversions use standard unit factors and are rounded for display. Temperature inputs below absolute zero are rejected.
When to use this tool
Convert measurements between the units used by different products, documents, or countries. Pick the measurement type first, then the source and target units. Length and weight conversions use multiplication factors; temperature conversions also involve an offset. The displayed result is rounded to keep it readable.
PRACTICAL EXAMPLE
Three useful reference conversions
- Start with
- 1 inch; 1 pound; 32 degrees Fahrenheit.
- What to expect
- These convert to 2.54 centimeters, 0.45359237 kilograms, and 0 degrees Celsius.
Get a better result
- Check the measurement type before converting. A fluid ounce measures volume and is not the weight ounce offered here.
- Keep enough precision for your task and round only the final result when doing several calculations.
Common questions
Can I convert cups to grams?
No. Cups measure volume and grams measure mass; the conversion depends on the substance’s density. This tool does not include volume or density conversions.
Why is a negative Kelvin temperature rejected?
This converter handles ordinary thermodynamic temperature scales and rejects inputs below absolute zero.
