Convert decimal numbers to scientific notation (a × 10^b), engineering notation, and E-notation.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Type any decimal number, large integer, or scientific expression.
Inspect scientific format (1 ≤ a < 10), engineering format (10^3x), and E-notation.
Copy the formatted mathematical notation with one click.
In scientific notation, the exponent can be any integer so the mantissa is between 1 and 10. In engineering notation, the exponent is always a multiple of 3 (e.g. 10^3, 10^6, 10^-6), aligning with metric prefixes like kilo, mega, and micro.
Significant figures are the digits in a number that carry meaningful precision contributing to its measurement resolution.
