Extreme heat advisory
Most US cities: 25-35°C (77-95°F)
South/Southwest: Can exceed 40°C (104°F)
Indoor AC: Usually 20-22°C (68-72°F)
💡 Bring layers - AC can feel cold!
Northern states: -20 to 5°C (-4 to 41°F)
Southern states: 5-20°C (41-68°F)
Indoor heating: 20-22°C (68-72°F)
💡 Check forecast - varies by region!
Iced drinks: Expect lots of ice (0°C/32°F)
Hot coffee: ~85°C (185°F)
Room temp water: Often cold (4-10°C/40-50°F)
💡 Ask for "no ice" if you prefer!
Oven 175°C: 350°F (most common)
Oven 200°C: 400°F (roasting)
Oven 230°C: 450°F (high heat)
💡 US ovens show Fahrenheit only!
The Formula
Example Calculation:
Problem: Convert 20°C to Fahrenheit
Step 1: 20 × 9/5 = 36
Step 2: 36 + 32 = 68
Answer: 68°F (room temperature)
For rough estimates: (°C × 2) + 30
Memorize common temperatures
Created: 1742 by Anders Celsius
Used in: Worldwide (except US and a few others)
Scale: Water freezes at 0°C, boils at 100°C (100° difference)
Best for: Science, international communication (metric system)
Created: 1724 by Daniel Gabriel Fahrenheit
Used in: United States, Cayman Islands, Bahamas, Palau
Scale: Water freezes at 32°F, boils at 212°F (180° difference)
Best for: Daily weather in US (finer granularity for comfort range)
While most of the world adopted the metric system and Celsius in the 1960s-70s, the United States maintained Fahrenheit due to the massive infrastructure costs of switching. American ovens, thermostats, weather forecasts, and medical equipment all use Fahrenheit.
For travelers and international visitors, having a Celsius to Fahrenheit conversion chart is essential for understanding weather forecasts, cooking recipes, and everyday temperature references in the United States.

20°C = 68°F. This is considered room temperature in most countries and is a comfortable indoor temperature. In the US, thermostats are often set to 68-72°F (20-22°C).
Use the formula: °F = (°C × 9/5) + 32. For example: (20°C × 9/5) + 32 = 68°F. For quick mental math, double the Celsius temperature and add 30 for a rough estimate: (20×2)+30 ≈ 70°F.
The US has maintained Fahrenheit since its founding. While most countries switched to Celsius with the metric system in the 1960s-70s, the US kept Fahrenheit due to infrastructure costs and cultural preferences. All American weather forecasts, ovens, and thermostats use Fahrenheit.
-40 degrees! -40°C = -40°F. This is the only point where the two temperature scales intersect. It's extremely cold - colder than the coldest inhabited places on Earth.
US summer temperatures vary by region. Northern states: 20-30°C (68-86°F), Southern states: 30-40°C (86-104°F). Indoor AC is typically set to 20-22°C (68-72°F), which can feel cold if coming from outside.
180°C = 356°F, which is typically rounded to 350°F (177°C) on US ovens. Most US ovens only display Fahrenheit. Common conversions: 175°C ≈ 350°F, 200°C ≈ 400°F, 230°C ≈ 450°F.
