Temperature Converter — Convert Celsius, Fahrenheit, and Kelvin instantly for cooking oven temps, weather, fever readings, and science homework.
0 Celsius = 32 Fahrenheit
0 °C = 32 °FUnit
Generated on May 24, 2026
Temperature conversion moves values between Celsius (the international standard for daily life, weather, and science), Fahrenheit (used mainly in the United States), and Kelvin (the scientific absolute scale). Unlike most unit conversions, temperature scales have different zero points and different step sizes — which is why simple multiplication isn't enough. This tool is useful for cooking (oven temperatures vary by recipe origin), medicine (US fever thresholds differ from metric ones), scientific study, travel, and reading international product manuals.
Formula
°F = (°C × 9/5) + 32. °C = (°F − 32) × 5/9. K = °C + 273.15.Temperature conversion has three big moments in real life: a US recipe that says 'bake at 375 degrees' and your oven dial only shows Celsius, a feverish child where the thermometer reads 102 Fahrenheit and you panic because your brain only knows 37 as normal, and a US-imported AC unit whose remote only does Fahrenheit. Each time, the wrong conversion has consequences — undercooked cake, unnecessary 3 AM hospital trip, freezing or boiling your guests in a Lahore drawing room. The basic rule is that Celsius and Fahrenheit are not just scaled differently, they have different zero points, which is why you cannot just multiply or divide — there is an offset. For cooking, every 25-degree Fahrenheit step is roughly 14 Celsius, so 350F = 175C is the one most cookbooks round to 180C. For body temperature, 100.4F is the medical fever threshold and equals exactly 38C — anything above either number is when most Pakistani paediatricians want a call. Honest take: just remember that minus 40 is the same in both scales (a useful party fact, if you ever go to Canada in February) and that 37C is normal body temperature; the rest the calculator can do.

Celsius and Fahrenheit differ in two independent ways: their zero points (0 °C = 32 °F) and their step sizes (180 Fahrenheit degrees span what 100 Celsius degrees span between water's freezing and boiling points, which is where the 9/5 ratio comes from). Kelvin shares Celsius's step size exactly but resets zero to absolute zero — the theoretical coldest temperature where all molecular motion stops. Because of these offsets, temperatures are converted by rescaling and shifting, not by simple factor multiplication like mass or length.

Room temperature (20 °C / 68 °F) is where most people feel comfortable without a jacket — the global standard for indoor offices.
Normal body temperature (37 °C / 98.6 °F) is the internal temperature the human body defends against weather extremes.
Water freezes at 0 °C (32 °F) — the origin point of the Celsius scale and a practical cue for ice warnings on weather apps.
Water boils at 100 °C (212 °F) at sea level; at higher altitudes (like Lahore's 217 m or Quetta's 1,680 m), it boils at a slightly lower temperature because air pressure is lower.
Absolute zero (−273.15 °C / −459.67 °F / 0 K) is the coldest possible temperature — no object has ever reached it.
Room temperature 25 °C equals 77 °F — useful when setting a US-branded air conditioner or thermostat.
An oven at 350 °F equals roughly 177 °C — the most-searched cooking conversion in the world.
Water freezes at 0 °C which equals 273.15 K — scientists prefer Kelvin because it avoids negative numbers in physics equations.
At exactly −40°, Celsius and Fahrenheit read the same number — a handy mnemonic for cold-climate travelers.
A fever of 100.4 °F is 38 °C — the medical threshold commonly used for a low-grade fever.
Comfortable living room temperature is 21 °C, which is 70 °F — an important conversion when adjusting US- or UK-style thermostats.
