Unit Converter
Converts length through metre ratios and mass through kilogram ratios. Temperature uses Celsius, Fahrenheit and Kelvin offsets and scale factors. Example: 2 metres × 0.001 = 0.002 kilometres.

Limits and verification
Supports metre, kilometre, international mile, foot, inch and yard; kilogram, gram, avoirdupois pound and ounce; Celsius, Fahrenheit and Kelvin. Values use binary64, not exact BigInt arithmetic. Length and mass results retain up to 12 significant digits. Display uses up to 12 significant digits, or 9 in scientific notation. Blank, non-finite, underflowing and overflowing conversions are rejected. Temperatures below absolute zero are rejected; rounding can prevent exact round trips near that boundary.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
How does this unit converter calculate results?+
Converts length through metre ratios and mass through kilogram ratios. Temperature uses Celsius, Fahrenheit and Kelvin offsets and scale factors. Example: 2 metres × 0.001 = 0.002 kilometres.
Which units and numeric limits apply?+
Supports metre, kilometre, international mile, foot, inch and yard; kilogram, gram, avoirdupois pound and ounce; Celsius, Fahrenheit and Kelvin. Values use binary64, not exact BigInt arithmetic. Length and mass results retain up to 12 significant digits. Display uses up to 12 significant digits, or 9 in scientific notation. Blank, non-finite, underflowing and overflowing conversions are rejected. Temperatures below absolute zero are rejected; rounding can prevent exact round trips near that boundary.
How do I convert 2 metres to kilometres?+
Select Length. Set Value to 2, From to Meter and To to Kilometer. Read the automatically updated converted value: 0.002.
Does this tool preserve arbitrary precision in round trips?+
No. Binary64 representation and display rounding can lose precision. Tiny nonzero results use scientific notation; zero is distinct from an invalid or unrepresentable result.
