Unit Conversion Guide: Metric, Imperial & Common Units
Key Points
- Most countries use metric (meters, kilograms), US uses imperial (feet, pounds)—easy to mix up
- Temperature conversion isn't linear—0°C = 32°F, not 0°F
- Data units: 1 KB = 1024 bytes (not 1000)—matters for large files
Traveling abroad and see height as 6 feet—how tall is that? Recipe calls for 2 cups flour—how many grams? Is 100 Mbps the same as 12.5 MB/s? Unit conversion is everywhere in daily life. Use this tool to quickly convert length, weight, temperature, volume, speed, and data size.

Metric length of 1 inch
Common Conversion Needs
Travel & Shopping
In the US buying ingredients, recipe says 1 gallon milk—how many liters? In Japan buying TV, 50-inch screen—how many cm? Height and weight conversion also common (6 feet = 183 cm, 150 lbs = 68 kg).
Cooking Recipe Conversion
Western recipes use cups, tablespoons, ounces, but Asian recipes use grams and milliliters. 1 cup flour ≈ 120g, 1 cup water ≈ 240ml. Accurate conversion ensures recipe success.
Science & Engineering Calculations
Engineering drawings may mix imperial (inches, feet) and metric (mm, meters). For precision parts, unit errors can be critical—converters ensure accuracy.
Network & Data Storage
Internet speed 100 Mbps (Megabits per second) = 12.5 MB/s (Megabytes per second). How long to download 1 GB file? Use converter to calculate quickly.
Common Conversion Pitfalls
Temperature formula: °F = °C × 9/5 + 32. Celsius 0° = Fahrenheit 32°, Celsius 100° = Fahrenheit 212°.
Data units: 1 KB = 1024 bytes, 1 MB = 1024 KB, 1 GB = 1024 MB (computers use 1024, not 1000).
Cooking: '1 cup' weight varies by ingredient—1 cup water ≠ 1 cup flour ≠ 1 cup sugar. Use kitchen scale for precision.
Imperial length memory: 1 inch = 2.54 cm, 1 foot = 12 inches = 30.48 cm, 1 yard = 3 feet.
Conversion results are rounded to several decimal places. For ultra-precise calculations, use professional tools.
