Length
mi = km × 0.62137ft = m × 3.28084in = cm × 0.39370Temperature
°F = (°C × 9/5) + 32°C = (°F − 32) × 5/9K = °C + 273.15Weight
lb = kg × 2.20462oz = g × 0.03527st = kg / 6.35029How It Works

Frequently Asked Questions
The Conversions People Get Wrong
Daily-life conversions, with the catch in each
Most conversion mistakes aren't math errors — they're using a remembered approximation where precision matters:
| Conversion | Exact-ish | Where people slip |
|---|---|---|
| kg ↔ lb | 1 kg = 2.2046 lb | Gym plates and luggage allowances |
| km ↔ miles | 1 km = 0.6214 mi | Treadmills and US speed limits |
| °C ↔ °F | ×9/5 + 32 | The +32 gets forgotten |
| feet/inches ↔ cm | 5'8" = 172.7 cm | Visa forms want one or the other exactly |
| liters ↔ gallons | US and UK gallons differ ~20% | Fuel economy comparisons |
The marla problem
Pakistan's favorite unit trap: a marla is 272.25 sq ft by the traditional standard but 225 sq ft in many housing schemes and cities — a 17% difference that's real money on a plot purchase. Kanal inherits the ambiguity (20 marlas either way). Before comparing plot prices per marla across societies, confirm which marla each one means; the honest comparison converts everything to square feet first.
When precision actually matters
Cooking forgives rounding; dosage, engineering, customs declarations and legal documents don't. The converter keeps full precision — round at the end, not in the middle, especially when chaining conversions (each early rounding compounds). Physics-flavored conversions have dedicated tools: speed–distance–time for travel math and density for mass–volume problems, with the scientific calculator for everything in between.
