Convert Decimal to Binary
You can quickly convert decimal to binary using this online tool. If you want to do the reverse then check out convert Binary to Decimal.
This tool can convert a regular whole number like "42" into a binary result - in this case the answer to everything would be "101010".
It can also do batch conversion for your numbers. Just make sure each number is on a separate line and your whole list of numbers will be converted automatically.
The computational capacity for this decimal number converter is governed by the capacity of whatever device you're using but in most cases it should be handle fairly large batches of base ten numbers if required.
NOTE: this dec to bin conversion tool will not work as expected with the number notation style popular in countries such as Germany or Denmark where for example one million (1,000,000 in USA, Canada, and etc) is commonly written as 1.000.000.
It also only uses whole numbers so if you enter something like 10.25 or 10.75, everything after the dot will be chopped off and you'll get the result for the whole number ten.
The Decimal Numeral System
One of the more interesting things I learned when putting this tool together was how wide the variety is on a global basis for the kinds of structures we use in writing down numbers.
I know about the dot notation style favored in Germany but I didn’t realize how many variations there are for number notation. Check out the table below or go read more on Wikipedia.
