String length data for DynamoDB

I try to convert the string length of 400KB (the maximum size of a DynamoDB item) to characters.

I don't know if KB is kilobytes (in this case 400 000 characters) OR kilobits (in this case 51 200 characters).

Do you know that ?

Thanks

Definitely 400 KiloBytes. But DynamoDb uses UTF-8 encoding for the strings. So if the your string is UTF-16 encoded, it may or may not fit as one dynamodb item. Secondly the 400KB limit also includes the binary length of the attribute key names you have in the table.

How many characters can UTF-8 encode?
