About Character to Token Calculator
Character to Token Calculator is used to convert a character count or word count into an estimated token count for LLM API cost and context window planning. It works by: it applies tokenizer-specific conversion ratios (approximately 4 characters per token for GPT-style tokenizers) to your character or word count. Token counts vary by language — English averages ~4 chars/token but Chinese and Japanese average ~1.5-2 chars/token, making multilingual apps more expensive per character. Character to Token Calculator runs free in your browser at abovetool.com — no signup required.
