Unit Converter - Taitham Numerals
Convert between units of length, weight, temperature, volume, area, time, and more with Taitham numeral system support.
About This Numeral System
Tai Tham numerals (᪐ through ᪙) are the digits of the Tai Tham script, also known as the Lanna or Tham script. This script is used for several Tai languages — primarily Northern Thai (Kham Mueang), Tai Lü, and Khün — across Northern Thailand, parts of Laos, and parts of Myanmar and China. The script has historically been used for Buddhist religious texts (Pali and Sanskrit) as well as for everyday writing in the Lanna kingdom. This calculator displays results in Tai Tham numerals for users who study or work with Northern Thai, Tai Lü, or the Lanna script tradition.
A free online unit converter for length, weight, temperature, volume, area, speed, time, data storage, energy, pressure, and angle. Convert between metric and imperial units instantly as you type — no need to press a convert button. Handles the tricky cases correctly: temperature conversions include the 32-degree offset (C to F is not simple multiplication), and volume conversions distinguish between US gallons (3.785 L) and Imperial gallons (4.546 L). Pin your most-used units for quick access. Supports traditional regional units like hath, gaz, tola, and ser used in South Asia.
How This Calculator Works
Unit Conversion: Result = Input × (source factor / target factor)
Each unit category (length, weight, volume, etc.) has a base unit and conversion factors. The calculator converts the input to the base unit, then from the base unit to the target unit. Temperature is a special case: C to F uses F = C × 9/5 + 32, because the zero points differ.
Frequently Asked Questions
How do I convert Celsius to Fahrenheit?
To convert Celsius to Fahrenheit, multiply by 9/5 and add 32: F = C × 9/5 + 32. For example, 25°C = 25 × 1.8 + 32 = 77°F. To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9: C = (F - 32) × 5/9. This calculator handles both directions automatically — just enter the value and select the units.
Why does my temperature conversion show a different result than expected?
Temperature conversions are not simple multiplication like other units. Celsius to Fahrenheit is F = C × 9/5 + 32, not F = C × 1.8. The offset of 32 is the most common source of error. Also, negative temperatures work correctly: -40°C = -40°F, which is the point where the two scales meet. The calculator handles all of these correctly, but if you are comparing with a tool that uses a simplified formula, the results will differ.
How do I convert between units that use different measurement standards (US vs Imperial)?
The most confusing case is volume: a US gallon is 3.785 litres while an Imperial (UK) gallon is 4.546 litres — a 20% difference. Similarly, a US pint is 473 ml while an Imperial pint is 568 ml. The calculator defaults to US units. If you need Imperial units, check the category label — where both exist, they are listed separately.
What unit categories are supported?
The unit converter supports length, weight/mass, temperature, volume, area, speed, time, data storage, energy, pressure, and angle conversions.
How accurate are the conversions?
All conversions use internationally recognised conversion factors. Results are displayed to up to 10 significant figures.
Is the Tai Tham script still used in everyday life in Northern Thailand?
Not in everyday writing — Northern Thai speakers now use the Thai script for daily communication. However, the Tai Tham script remains in active use for Buddhist religious texts, temple inscriptions, and traditional manuscripts in Northern Thailand, Laos, and among Tai Lü and Khün communities. It is studied by monks, scholars, and cultural preservationists. The numerals appear in religious and historical contexts rather than in markets or government documents.
Worked Examples
Input: Convert 10 miles to kilometres
Result: 10 miles = 16.0934 km (1 mile = 1.60934 km)
Input: Convert 100°C to Fahrenheit
Result: F = 100 × 9/5 + 32 = 212°F (boiling point of water)
