How it works
A sentence ends at a full stop, question mark or exclamation mark. Abbreviations with full stops can make the count of sentences too high.
The scores were made for running text and are only a rough guide for short abstracts.
Flesch: 206.835 − 1.015 × (words ÷ sentences) − 84.6 × (syllables ÷ words)Flesch–Kincaid grade: 0.39 × (words ÷ sentences) + 11.8 × (syllables ÷ words) − 15.59Ateşman: 198.825 − 40.175 × (syllables ÷ words) − 2.610 × (words ÷ sentences)
Worked example: "The cat sat on the mat." has 6 words, 6 syllables and 1 sentence: score 116.1.

Questions
What is a good score?
Scientific text usually scores 20 to 40 on the Flesch scale, which is difficult. A higher score means shorter sentences and shorter words, not better science.
Is the syllable count exact?
Turkish syllables are counted exactly (one per vowel). English syllables are estimated by rules, so the score can be a few points off.
