About this tool
The Unit Converter provides immediate, bidirectional conversions across essential metric and imperial measurement standards, including length, speed, temperature, and mass.
International collaboration often requires switching between meters and feet, Celsius and Fahrenheit, or kilograms and pounds. Our converter uses exact scientific conversion factors to produce clean, rounded results suitable for engineering, cooking, fitness, and travel.
Runs 100% locally in your browser. Perform quick conversions on the fly without ads blocking your view or unnecessary network requests.

Precisión técnica
All computations utilize standard double-precision 64-bit floating point arithmetic. Rounding is performed transparently to four significant decimal places to eliminate common binary floating-point display artifacts while preserving precision.
Preguntas frecuentes
How are percentages calculated?
Three standard formulas are supported:
1. Value: (Percentage ÷ 100) × Base
2. Proportion: (Part ÷ Total) × 100
3. Percentage change: ((New Value − Old Value) ÷ |Old Value|) × 100
Which conversion constants are used for unit conversions?
Conversions adhere to NIST and International System of Units (SI) standards: 1 inch is exactly 2.54 cm, 1 international mile is 1.609344 km, 1 pound avoirdupois is exactly 0.45359237 kg, and temperature conversions use the exact ratio (°F = °C × 9/5 + 32).
Can I use the basic calculator with my computer keyboard?
Yes. The basic calculator supports both clicking the on-screen high-contrast keypad and direct keyboard input (numbers 0–9, +, -, *, /, Enter for equals, and Escape or C for clear).
Are my numbers or calculations tracked?
No. All mathematical operations are processed in local memory inside your web browser. No figures are logged, transmitted, or shared.
