Parts and their functions
- Celsius scale (°C) (सेल्सियस पैमाना (°C)) — 0 °C (ice melts) to 100 °C (water boils), divided into 100 equal parts.
- Fahrenheit scale (°F) (फ़ॉरेनहाइट पैमाना (°F)) — 32 °F to 212 °F (180 divisions). °F = (9/5)(°C) + 32.
- Kelvin scale (K) — SI unit (केल्विन पैमाना (K) — SI मात्रक) — K = °C + 273.15. No negative values on the Kelvin scale; 0 K is absolute zero.
- Same temperatures, three numbers (एक ही ताप, तीन संख्याएँ) — Each dashed line is one temperature read on all three scales.
