Scientific Notation Converter

The Scientific Notation Converter lets you flip between standard numbers and scientific notation with ease. Whether you’re working with large numbers like 4500000 or tiny decimals like 0.00056, this tool transforms them into compact scientific form like 4.5 × 10^6 or 5.6e-4.

You can also go the other way: enter scientific notation in either e format (1.23e5) or ×10^ style, and instantly convert it back to a regular decimal. It’s perfect for data cleanup, scientific calculations, or when you’re prepping values for reports or programming.

Everything updates live. As soon as you change anything, the output refreshes and the blue border flash lets you know. You can round results to 3 significant figures, toggle the visual style, and trim empty lines. It’s fully browser-based and runs lightning-fast.

Options
Round to 3 sig figs
Use ×10^ format
Trim empty lines
