Unit Converter: Metric to Imperial Conversions Made Simple

Why Unit Conversion Trips People Up

Half the world uses metric (metres, kilograms, Celsius) and the other half uses imperial (feet, pounds, Fahrenheit). Recipes, workouts, travel, and school work all mix the two, and a wrong conversion can ruin a recipe or a measurement.

The Unit Converter handles length, weight, temperature, and more instantly — here is how the common ones work.

Length Conversions

Metric	Imperial
1 cm	0.39 inch
1 m	3.28 feet
1 km	0.62 mile
1 foot	30.48 cm
1 mile	1.61 km

Quick mental math: km × 0.6 ≈ miles, and feet × 30 ≈ cm.

Weight Conversions

Metric	Imperial
1 kg	2.20 pounds
1 g	0.035 ounce
1 pound	0.45 kg
1 ounce	28.35 g

A rough shortcut: kg × 2.2 ≈ pounds.

Temperature Conversions

Temperature is not a simple multiply, so use a formula:

• Celsius to Fahrenheit: °F = (°C × 9/5) + 32
• Fahrenheit to Celsius: °C = (°F − 32) × 5/9

So 30°C = 86°F, and 100°F = 38°C (a body fever check people often need).

Other Everyday Conversions

Type	Example
Volume	1 litre = 0.26 gallon, 1 cup = 240 ml
Area	1 acre = 4047 m², 1 sq ft = 0.093 m²
Speed	1 km/h = 0.62 mph
Data	1 GB = 1024 MB, 1 MB = 1024 KB

For data sizes, the Time Calculator and Percentage Calculator are handy companions when tasks mix units and math.

How to Convert Instantly

1. Open the Unit Converter.
2. Pick the category (length, weight, temperature, and more).
3. Enter the value and choose the units.
4. Read the converted result and copy it.

FAQ

Why does the US use imperial units? Historical reasons — the US adopted the imperial system early and kept it, while most of the world standardised on metric.

Is 1 GB equal to 1000 MB or 1024 MB? Technically 1024 MB is 1 gibibyte (GiB), but storage is often marketed using 1000. The Unit Converter shows both conventions clearly.

How do I convert Celsius to Fahrenheit quickly? Double the Celsius temperature and add 30 for a rough estimate: 20°C → 50 (actual 68°F). Use the exact formula for anything important.
