How Unit Conversion Works

This converter supports five categories: Volume, Area, Speed, Time, and Digital Storage. Each category uses a base unit for conversion.

All conversions work by first converting the input to the base unit, then converting from the base unit to the target unit. This ensures accuracy across all unit combinations.

Base units: Volume → Liters, Area → Square Meters, Speed → Meters/second, Time → Seconds, Data → Bytes. Digital storage uses binary prefixes (1 KB = 1024 bytes).

Unit converter FAQs

Answers to common questions about unit conversion.

Does this use metric or binary prefixes for data?

Binary prefixes (1 KB = 1024 bytes, 1 MB = 1,048,576 bytes). This matches how operating systems and programming typically measure file sizes and memory.

How many cups in a gallon?

16 cups = 1 gallon. Also: 4 quarts = 1 gallon, 2 pints = 1 quart, 2 cups = 1 pint.

What's the difference between a hectare and an acre?

1 hectare = 2.471 acres. A hectare is 10,000 m² (100m × 100m). An acre is 43,560 ft² (approximately 208.71 ft × 208.71 ft). Hectares are used internationally; acres in the US and UK.

Why are there different unit systems?

The metric system was developed in France during the 1790s for universal standardisation. The imperial system evolved from earlier English units. Most countries adopted metric, but the US, Liberia, and Myanmar still primarily use imperial/customary units.
