How it is calculated
Tokens = pages × words per page × tokens per word. English text is often around 1.3 tokens per word; German and Turkish usually need more because words are longer and carry more suffixes.
Keep in mind
This is an estimate. Each model has its own tokenizer, so measure a sample of your real text when the number matters.
