Unit conversions are calculated in your browser. The values you enter are not sent to Nimzoa's application servers for conversion. Website analytics are separate from your calculation inputs.
Length, weight/mass, temperature, area, volume, speed, time and data storage are available.
An international inch is exactly 0.0254 meters, a pound is exactly 0.45359237 kilograms, and a US gallon is exactly 3.785411784 liters. An acre is 43,560 square feet.
Celsius, Fahrenheit and Kelvin use scale offsets and ratios, with absolute-zero validation; temperatures below absolute zero are rejected.
A kilobyte (KB) contains 1,000 bytes, while a kibibyte (KiB) contains 1,024 bytes. The same decimal versus binary distinction applies to larger prefixes; 8 bits equal 1 byte.
No. All conversions happen in your browser. Values are not uploaded, tracked or stored.
Select the relevant category, enter your metric value, then choose the metric unit under From Unit and the corresponding imperial or US customary unit under To Unit. The result and formula appear automatically.
One meter equals approximately 3.28084 feet. For example, 5 meters equals approximately 16.4042 feet. Use the Length category to convert other values.
MB means megabyte and uses the decimal system: 1 MB equals 1,000,000 bytes. MiB means mebibyte and uses the binary system: 1 MiB equals 1,048,576 bytes. They are different units, so choose the correct prefix when converting digital storage.

Different countries and industries use different measurement systems. Metric units such as meters, kilograms, and liters are common internationally, while feet, pounds, and US gallons are also widely used.
A metric to imperial converter helps you compare measurements without calculating every conversion factor manually.
For example:
Measurement | Conversion |
|---|---|
1 meter | Approximately 3.28084 feet |
1 inch | Exactly 2.54 centimeters |
1 kilogram | Approximately 2.20462 pounds |
1 mile | Exactly 1.609344 kilometers |
1 US gallon | Approximately 3.78541 liters |
Conversion results may be rounded for display. Use the correct unit type, especially when distinguishing US and imperial volume measurements.
Length conversion is useful for measuring height, distance, furniture, room dimensions, and construction materials.
Common length conversions include meters to feet, feet to meters, centimeters to inches, and inches to centimeters.
To convert meters to feet, multiply the number of meters by approximately 3.28084.
Example: 5 meters × 3.28084 = approximately 16.4042 feet.
To convert centimeters to inches, divide the centimeter value by 2.54.
Example: 30 cm / 2.54 = approximately 11.811 inches.
You can also reverse the selected units to convert inches back to centimeters.
A weight converter is helpful when comparing body weight, ingredient quantities, shipping weights, and product specifications.
The unit category is labeled Mass in the converter, although people often search for these calculations using the word weight.
One kilogram equals approximately 2.20462 pounds.
Example: 10 kg × 2.20462 = approximately 22.0462 lb.
One gram equals approximately 0.035274 avoirdupois ounces.
Example: 100 g × 0.035274 = approximately 3.5274 oz.
Be careful to distinguish ounces used for mass from fluid ounces used for volume.
Temperature conversion differs from many other unit conversions because Celsius and Fahrenheit have different zero points.
°F = (°C × 9 / 5) + 32
Example: 25°C = 77°F.
°C = (°F − 32) × 5 / 9
Example: 68°F = 20°C.
These formulas are useful for weather forecasts, cooking temperatures, and everyday temperature comparisons.
Area measures the size of a two-dimensional surface, such as a room, floor, or piece of land.
One square meter equals approximately 10.7639 square feet.
Example: 20 square meters × 10.7639 = approximately 215.278 square feet.
Area conversion factors are different from ordinary length conversion factors. You cannot convert square meters to square feet using the meters-to-feet factor only once.
Volume conversions are useful for liquids, containers, recipes, and capacity measurements.
One US liquid gallon equals approximately 3.78541 liters.
Example: 2 US gallons × 3.78541 = approximately 7.57082 liters.
US liquid gallons and imperial gallons are different units. Always select the appropriate unit when both are available.
Speed conversion is useful for travel, vehicle specifications, and comparing speed limits.
One kilometer per hour equals approximately 0.621371 miles per hour.
Example: 100 km/h × 0.621371 = approximately 62.1371 mph.
To reverse the calculation, convert miles per hour to kilometers per hour using the corresponding units in the converter.
Time conversion helps with schedules, durations, study sessions, and everyday calculations.
Common relationships include:
1 minute = 60 seconds
1 hour = 60 minutes
1 hour = 3,600 seconds
1 day = 24 hours
Example: 2.5 hours × 60 = 150 minutes.
These conversions concern units of duration. They are different from converting between calendar dates or time zones.
Digital storage conversions can be confusing because decimal and binary prefixes use different bases.
Decimal units use powers of 1,000:
1 kilobyte (kB) = 1,000 bytes
1 megabyte (MB) = 1,000,000 bytes
1 gigabyte (GB) = 1,000,000,000 bytes
Binary units use powers of 1,024:
1 kibibyte (KiB) = 1,024 bytes
1 mebibyte (MiB) = 1,048,576 bytes
1 gibibyte (GiB) = 1,073,741,824 bytes
Using decimal storage units, divide megabytes by 1,000.
Example: 2,500 MB / 1,000 = 2.5 GB.
For binary units, use MiB and GiB rather than treating MB and MiB as interchangeable.
Nimzoa distinguishes decimal and binary prefixes so you can select the appropriate measurement.
Conversion | Formula |
|---|---|
Meters to feet | meters × 3.28084 |
Centimeters to inches | centimeters / 2.54 |
Kilograms to pounds | kilograms × 2.20462 |
Celsius to Fahrenheit | (Celsius × 9 / 5) + 32 |
Fahrenheit to Celsius | (Fahrenheit − 32) × 5 / 9 |
Square meters to square feet | square meters × 10.7639 |
US gallons to liters | gallons × 3.78541 |
KM/H to MPH | km/h × 0.621371 |
Hours to minutes | hours × 60 |
Decimal MB to GB | MB / 1,000 |
Factors shown with rounded decimal values give approximate results.
Instead of searching for a separate calculator every time you need a different measurement, you can use one tool for eight categories.
