Frequently Asked Questions
What is the formula to convert Celsius to Fahrenheit?
The formula is: °F = (°C × 9/5) + 32. To convert 35°C (a typical hot Indian summer day) to Fahrenheit: (35 × 1.8) + 32 = 95°F. The reverse formula is °C = (°F − 32) × 5/9. A quick mental trick: double the Celsius value and add 30 for a rough Fahrenheit estimate. So 40°C ≈ 110°F (actual: 104°F).

What is the normal human body temperature in Celsius?
Normal body temperature is approximately 37°C (98.6°F). In India, a fever is typically considered when temperature rises above 38°C (100.4°F). High fever is above 39.5°C (103.1°F) and requires medical attention. Thermometers in India mostly display Celsius, but some imported digital thermometers show Fahrenheit — 98.6°F is normal, 100.4°F indicates fever, and 104°F is a high fever requiring immediate attention.

Why do weather apps show different temperatures for the same city?
Different apps may display temperature in Celsius or Fahrenheit depending on your device's regional setting. Indian weather apps like IMD, Skymet and Accuweather default to Celsius. If your phone is set to US locale, it shows Fahrenheit. For example, Delhi's peak summer temperature of 45°C shows as 113°F. To switch units in your phone's weather app, change the temperature unit in the app settings or your phone's region to India.

What oven temperature should I use for baking in Celsius vs Fahrenheit?
Most Indian microwave ovens and OTGs (oven-toaster-grills) display temperature in Celsius, while many international baking recipes use Fahrenheit. Common conversions: 180°C = 356°F (standard baking for cakes), 200°C = 392°F (cookies and bread), 220°C = 428°F (pizza and roasting). A recipe asking for 350°F means set your Indian oven to 175-180°C. Use the free Temperature Converter on AbacusHand to calculate your exact result instantly.
What temperature is considered a fever in India and when to see a doctor?
In India, a temperature above 38°C (100.4°F) is classified as fever. Mild fever (38–38.5°C) can be managed with paracetamol and rest. Moderate fever (38.5–39.5°C or 101–103°F) requires medical consultation, especially in children under 5. High fever above 39.5°C (103°F) or any fever with rash, convulsions or difficulty breathing requires emergency care. Seasonal diseases like dengue, typhoid and malaria common in India can cause sustained high fevers of 39–40°C.
