Metric vs Imperial length units
The metric system (SI) is the international standard. It uses millimetres (mm), centimetres (cm), metres (m), and kilometres (km), where each unit is a power of 10 apart. The metric system is used in science and by most countries worldwide.
The imperial system uses inches, feet, yards, and miles. It remains in everyday use in the United States and partially in the UK. The critical conversion anchor is 1 inch = 2.54 cm exactly — all other imperial-to-metric conversions derive from this.
This converter works by normalising every value to metres first, then converting to the target unit using precise SI-defined ratios — so chained conversions (e.g. inches → km) are always accurate.
