Good to know
Linear units use fixed factors. One pyeong is 400/121 square metres; Fahrenheit is Celsius × 9/5 + 32. Temperatures below absolute zero are rejected.

Understand and use your results
Compare measurements written in different units of length, area, mass or temperature. Conversions stay within one dimension and use fixed relationships rather than live rates.
How to use it
- Choose the dimension, then the source and destination units.
- Enter the value and read the output unit. Area conversions use different factors from length.
Worked example
1 mi → km
1.609344 km
One mile is 1.609344 kilometres. Temperature also involves an offset, so 32°F equals 0°C. Displayed results use up to 12 significant digits.
How are pyeong and temperature limits handled?
One pyeong is treated as 400/121 square metres. Temperatures below absolute zero are rejected. Different dimensions such as kilograms and metres cannot be converted, and measurement error is not corrected.
