Temperature
Temperature needs a formula rather than a multiplier, because the scales have different zero points:
°F = (°C × 9/5) + 32
°C = (°F − 32) × 5/9
K = °C + 273.15
| Celsius | Fahrenheit | Context |
|---|---|---|
| 0°C | 32°F | Water freezes |
| 37°C | 98.6°F | Normal body temperature |
| 40°C | 104°F | Indian summer afternoon |
| 100°C | 212°F | Water boils at sea level |
| 180°C | 356°F | Common baking temperature |
Mental shortcut: double the Celsius figure and add 30 for a rough Fahrenheit estimate. 25°C gives about 80°F — close enough for weather.

Indian units you'll still meet
- Quintal — 100 kg. Standard in agricultural trade and crop pricing.
- Tola — about 11.66 grams. Still used for gold in some markets.
- Maund — historically around 37.3 kg, though it varied regionally.
- Seer — roughly 0.93 kg, largely replaced by the kilogram.
- Gaj — the square yard, used in property.
For land and property area specifically, use the area unit converter, which handles bigha, guntha, cent and the other regional units.
Common mistakes
- Converting temperature with a multiplier instead of the formula.
- Mixing US, metric and imperial cups in a recipe.
- Confusing fluid ounces (volume) with ounces (weight).
- Rounding too early in multi-step conversions.
Frequently Asked Questions
How do I convert kg to pounds?
Multiply by 2.2046. So 70 kg is about 154.3 pounds.
How do I convert Celsius to Fahrenheit?
Multiply by 9/5 and add 32. For a rough mental estimate, double the Celsius figure and add 30.
How many cm is 5 feet 6 inches?
167.64 cm. Multiply total inches by 2.54 — 66 inches in this case.
Is a cup the same everywhere?
No. A US cup is 240 ml, a metric cup 250 ml and an imperial cup 284 ml. For baking, weighing in grams avoids the problem.
What is a quintal?
100 kilograms. It is widely used in Indian agricultural trade and crop price reporting.
What is the difference between an ounce and a fluid ounce?
An ounce measures weight, about 28.35 grams. A fluid ounce measures volume, about 29.57 ml. They are not interchangeable.
How do I convert km to miles?
Multiply by 0.6214. So 100 km is about 62 miles.
Rasoi ke maap
| Maap | Millilitre | Gram (aata) | Gram (cheeni) |
|---|---|---|---|
| 1 chhoti chammach (tsp) | 5 ml | ~3 g | ~4 g |
| 1 badi chammach (tbsp) | 15 ml | ~8 g | ~12 g |
| 1 cup | 240 ml | ~120 g | ~200 g |
| 1 katori | ~150 ml | — | — |
Dhyan rakhiye — 1 cup aata aur 1 cup cheeni ka wajan alag hota hai. Volume same hai, density alag. Baking mein isi wajah se gram mein taulna zyada bharosemand hota hai.
Mileage ke units
India mein kmpl chalta hai, lekin videshi reviews mein doosre units milte hain:
| kmpl | mpg (US) | litre/100km |
|---|---|---|
| 10 | 23.5 | 10.0 |
| 15 | 35.3 | 6.7 |
| 20 | 47.0 | 5.0 |
| 25 | 58.8 | 4.0 |
Ek baat samajh lijiye: kmpl mein zyada behtar hai, lekin litre/100km mein kam behtar hai — ye ulta chalta hai aur log aksar dhokha kha jaate hain.
More questions
1 cup kitne ml hota hai?
Standard cup 240 ml ka hota hai. Lekin cup mein wajan cheez par nirbhar karta hai — 1 cup aata lagbhag 120 g, jabki 1 cup cheeni lagbhag 200 g.
kmpl ko litre/100km mein kaise badlein?
100 ko kmpl se divide kar dijiye. 20 kmpl ka matlab 5 litre/100km. Yaad rakhiye, is unit mein chhota number behtar hota hai.
