How Many Characters Is 1 Million Tokens?
One million tokens is approximately 4,000,000 characters of English text. One token is roughly 4 characters — enough to fill 8,000 standard text messages.

Understanding token-to-word conversions is essential for developers budgeting API calls and for businesses estimating costs before committing to an AI provider. When every API call is metered by the token, knowing exactly how far your budget stretches can mean the difference between a viable product and an unexpectedly expensive one.
