Unit Conversion Guide — Length, Weight, Temperature and More

Unit conversion is a daily necessity — whether you are following a recipe from an American cookbook, calculating land area for a property deal in India, or converting bandwidth for a cloud architecture. This guide covers the most common conversions with practical examples.

Metric vs Imperial — The Basics

Length:
  1 kilometre = 0.621 miles
  1 metre     = 3.281 feet = 39.37 inches
  1 centimetre = 0.394 inches

Weight:
  1 kilogram = 2.205 pounds
  1 gram     = 0.035 ounces

Volume:
  1 litre    = 0.264 US gallons = 1.76 UK pints
  1 mL       = 0.034 US fl oz

Temperature Conversion

Celsius to Fahrenheit:  F = (C × 9/5) + 32
Fahrenheit to Celsius:  C = (F − 32) × 5/9
Celsius to Kelvin:      K = C + 273.15

Common references:
  0°C   = 32°F   (freezing)
  20°C  = 68°F   (room temperature)
  37°C  = 98.6°F (body temperature)
  100°C = 212°F  (boiling)

Indian Land Area Units

Note: values vary by state — these are approximate national averages

1 Bigha    ≈ 1,337 m² (varies: 843–6,771 m² by state)
1 Biswa    ≈ 133.7 m²  (1/10 Bigha)
1 Katha    ≈ 66.9 m²
1 Guntha   ≈ 101.2 m²
1 Acre     = 4,047 m²  = 43,560 sq ft
1 Hectare  = 10,000 m² = 2.471 acres

Digital Storage Units

8 bits     = 1 Byte
1,024 B    = 1 Kilobyte (KB)
1,024 KB   = 1 Megabyte (MB)
1,024 MB   = 1 Gigabyte (GB)
1,024 GB   = 1 Terabyte (TB)

Note: storage manufacturers use 1,000 (not 1,024) per unit
