Unit Converter
Quickly convert commonly used units. Supports area (pyeong/sq meters), length, weight, temperature, and data storage units.
1 Pyeong = 3.305785 m² | 10 Pyeong = 33 m² | 30 Pyeong = 99 m²
Things to Know
Unit conversions trip people up more often than you would expect. Here are some practical answers to the questions that come up most frequently.
How It Works
The unit converter uses conversion factor tables for unit transformations. Each category (length, weight, temperature, volume, etc.) has a base unit, with all units stored as ratios to it. Conversion first transforms to the base unit, then to the target. Temperature uses separate formulas (°C = (°F - 32) × 5/9) since it is not a linear ratio.

What is a Unit Converter?
A unit converter is a practical online tool that lets you quickly and accurately convert values between different measurement systems. Whether you need to switch between metric and imperial units or handle specialized conversions like Korean pyeong to square meters, this tool covers five essential categories: area, length, weight, temperature, and data storage. Results appear instantly as you type, with no installation or sign-up required.
Unit conversions come up more often than most people realize. Travelers need to understand foreign weather forecasts in Fahrenheit or Celsius. Online shoppers buying from international stores need to convert inches to centimeters for clothing sizes, or pounds to kilograms for shipping weight. Students working through physics or chemistry problems frequently convert between Kelvin and Celsius. This tool handles all of these scenarios and more, right in your browser.
User Guide
- Select the measurement category from the tabs at the top (Area, Length, Weight, Temperature, or Data).
- Enter the numeric value you want to convert in the left input field.
- Choose the source unit from the dropdown next to the input field.
- Choose the target unit from the dropdown next to the result field.
- The converted result appears automatically, calculated with decimal precision.
- Click "Swap Units" to reverse the conversion direction along with the current value.

Common Questions
Q: What measurement categories are supported?
This converter supports five categories: area (pyeong, square meters, square feet), length (cm, m, km, inches, feet, miles), weight (kg, g, pounds, ounces), temperature (Celsius, Fahrenheit, Kelvin), and data storage (bytes, KB, MB, GB, TB).
Q: How accurate are the conversions?
All conversions use internationally standardized conversion factors. Results are computed to 10 significant digits. This level of precision is more than sufficient for everyday use, though specialized scientific or engineering applications may require dedicated tools.
Q: What is the difference between metric and imperial systems?
The metric system (SI units) is based on powers of 10 and uses meters, kilograms, and liters. It is the standard in most countries. The imperial system, used primarily in the United States, uses feet, pounds, and gallons. Metric is generally easier for calculations because of its consistent decimal structure.
Q: How many centimeters is 1 inch?
One inch equals exactly 2.54 cm. Screen sizes (monitors, TVs) are measured diagonally in inches. For example, a 27-inch monitor has a diagonal length of about 68.6 cm.
Q: How many kilograms is 1 pound?
One pound (lb) equals approximately 0.4536 kg (453.6 g). Conversely, 1 kg is about 2.205 lb. This conversion is especially useful when calculating shipping costs for international orders.
Q: How many kilometers is 1 mile?
One mile equals approximately 1.609 km. When driving in the US, a speed limit of 65 mph translates to about 105 km/h.
Q: What is the Celsius to Fahrenheit formula?
°F = °C x 9/5 + 32. Useful reference points: water freezes at 0°C (32°F), boils at 100°C (212°F), and normal body temperature is 36.5°C (97.7°F).
Q: How many GB is 1 TB?
Using binary units, 1 TB = 1,024 GB. A 1 TB hard drive will show slightly less usable space because the operating system and file system overhead consume a small portion.
Q: Is my data collected or sent to a server?
No. All calculations happen entirely in your browser. No values are transmitted to or stored on any server. Once the page loads, you can even use it offline.
Q: Does this work on mobile devices?
Yes. The tool uses responsive design and works on smartphones and tablets. No app installation is needed -- just open it in your mobile browser.
