Frequently asked questions
Why does a 1 TB drive show up as about 931 GB?
Drive makers use SI prefixes (1 TB = 1,000,000,000,000 bytes), while Windows counts in 1024s but still writes “GB”. In the Data size category, compare TB with TiB to see the difference. Network speeds are usually in bits: 100 Mbit/s is about 12.5 MB/s.
Why isn't 0 °C equal to 0 °F?
Temperature scales have different zero points, so they convert with an offset: 0 °C is 32 °F. A temperature difference converts by the factor alone, so a 1 °C step equals a 1.8 °F step.
How do L/100 km and mpg convert?
Fuel economy is not linear. L/100 km and gal/100 mi measure consumption (lower is better), while km/L and mpg measure distance per fuel (higher is better), so doubling one halves the other.
Does it convert currencies?
No. Currency rates change constantly and need live data, so there is no currency category. All 16 categories use fixed conversion factors and work offline.
Can I type commas as decimal separators?
Yes. You can type 12.5, 12,5 or 1,250; the field accepts a dot or your language's decimal comma and ignores grouping separators.
Which cup does the Cooking category use?
Several are listed: US cup (236.6 mL), metric cup (250 mL), Japanese cup (200 mL), UK cup and the 合 rice cup. Recipes from the US use US measures.
