About

Custom Unit Converter

Features
Read full description

MyUnit is a flexible unit conversion app that lets you freely add your own categories and units. In addition to standard conversions such as length, area, volume, temperature, weight, and speed, MyUnit also supports specialized units used in engineering, science, research, and business, including flow rate, pressure, vacuum, energy, power, force, resistance, frequency, and more. Many unit conversion apps only support pre-installed units. This can be inconvenient when the unit you need is missing or when the app does not fit your workflow. MyUnit solves this by allowing you to create your own categories and add the units you need. For example, you can create categories such as Pressure, Flow Rate, Temperature, or Vacuum, and register units such as Pa, psi, sccm, slpm, Torr, and more. MyUnit also supports multi-step calculations. In addition to simple multiplication-based conversion, you can create flexible conversion rules using ×, ÷, +, −, and ^. This makes it easier to handle conversions that cannot be expressed with only one simple factor. If you often calculate special formulas manually, MyUnit can help you save time. With this update, MyUnit now supports CSV export. You can export registered categories, units, and conversion data in CSV format. This makes it easier to check, organize, record, and share the data you created in the app. CSV export is useful for reviewing unit lists in spreadsheet software, organizing conversion rules, keeping research or work records, sharing data, and creating documents. Main Features 1. Add categories and units freely Create your own categories and register the units you need. 2. Multi-step calculations Create custom conversion rules using ×, ÷, +, −, and ^. 3. CSV export Export registered categories, units, and conversion data as CSV files. 4. Automatic conversion Enter one value and other units in the same category are automatically calculated. 5. Easy copy operation Copy conversion results quickly for reports, notes, emails, documents, and spreadsheets. 6. Rearrange categories and units Place frequently used categories and units at the top for faster access. 7. Useful for technical fields Suitable for engineering, science, research, experiments, design, development, evaluation, maintenance, and on-site checks. 8. Useful for everyday conversion Also convenient for daily conversions such as length, temperature, weight, volume, area, and speed. Recommended For ・People who want to add their own categories and units ・People who handle engineering, scientific, or technical units ・Researchers, students, engineers, technicians, and developers ・People who check overseas specifications or technical documents ・People who want to manage conversion data with CSV files Use Cases Students and researchers Useful for assignments, reports, experiments, research data, and unit conversion records.
