Frequently Asked Questions

How do I convert binary to decimal?

Type your binary number (using only 0s and 1s) into the Binary field — the Decimal field updates instantly with the equivalent value.

Is there a limit on how large a number I can convert?

Very large numbers beyond about 15 digits may lose precision due to standard floating-point number limits in the browser.
