Unit Converter Tool Guide
We often need to convert between units—temperature (Celsius and Fahrenheit), length (meters and feet), weight (kilograms and pounds), and more. SheetEdit Tools offers free online unit converters. All calculations run in your browser; no data is uploaded. This guide covers common conversion scenarios and usage tips.
What is unit conversion?
Unit conversion means expressing the same physical quantity in different measurement units (e.g., miles → kilometers, °F → °C). You multiply or divide by fixed conversion factors; the underlying value does not change. SheetEdit bundles many everyday and technical converters so you do not have to look up formulas manually.
Supported conversion types
Basic units
- Temperature: Celsius (°C), Fahrenheit (°F), Kelvin (K). For cooking, weather, and science.
- Length: Meters, centimeters, millimeters, kilometers, inches, feet, yards, miles. For construction, tailoring, travel.
- Weight: Grams, kilograms, pounds, ounces, tons. For cooking, fitness, logistics.
- Area: Square meters, hectares, mu, square feet, acres. For real estate, agriculture.
- Volume: Liters, milliliters, cubic meters, gallons, cubic feet. For cooking, liquids.
Time and speed
- Time: Seconds, minutes, hours, days, weeks, years. For scheduling, project duration, time tracking.
- Speed: m/s, km/h, mph, knots. For transport, sports, navigation.
Physical quantities
- Angle: Degrees, radians, gradians. For math, engineering, geography.
- Pressure: Pascal, bar, psi, atmosphere, mmHg. For tire pressure, weather, industry.
- Energy: Joules, calories, kWh, horsepower. For nutrition, electricity, exercise.
Data and number bases
- Data storage: Bytes, KB, MB, GB, TB, PB. For file size, storage capacity.
- Number base: Binary, octal, decimal, hexadecimal. For programming, networking, crypto.
- Timestamp: Unix timestamp and date/time conversion. For development, logging, APIs.
Number formats
- Roman numerals: Arabic and Roman (1–3999).
- Chinese numerals: Arabic and Chinese uppercase (壹贰叁肆) for invoices, checks, contracts.
- Scientific notation: Regular numbers and scientific notation for very large or small values.
Usage tips
Real-time conversion
Enter a value in any unit; others update instantly. Start with the unit you know best—e.g., Celsius in metric regions, Fahrenheit in the US.
Precision and rounding
The tool keeps reasonable precision; very large or small values may use scientific notation. For more decimal places, verify manually if needed.
Quick reference
- Temperature: 0°C = 32°F = 273.15K; 100°C = 212°F = 373.15K.
- Length: 1 inch ≈ 2.54 cm; 1 foot = 12 inches ≈ 30.48 cm.
- Weight: 1 pound ≈ 453.59 g; 1 ounce ≈ 28.35 g.
- Volume: 1 US gallon ≈ 3.785 L; 1 UK gallon ≈ 4.546 L.
FAQ
Q: Can I convert in bulk?
A: Currently single conversions only. For bulk, repeat or use spreadsheet formulas.
Q: Is data uploaded?
A: No. All conversions run locally in your browser.
Q: How do I convert uncommon units?
A: Convert to SI units (e.g., meters, kilograms) first, then to the target unit. Or use specialized conversion tables.
