FAQ
How are เอ็ด and ยี่สิบ written?
A final digit of 1 after a tens digit is read เอ็ด, so 21 baht is ยี่สิบเอ็ดบาท, and 20 is ยี่สิบ.
Can I include satang?
Yes. Type a decimal point and the satang, for example 150.75.
How many years apart are BE and AD?
543 years. Add 543 to an AD year to get the BE year, so AD 2025 is BE 2568.
What if I am not sure whether I typed BE or AD?
The birth year box decides for you. A number of 2400 or more is treated as BE, anything smaller as AD.
How many hours apart are Thailand and New York?
Thailand is UTC+7. New York is UTC−5 in winter (EST) and UTC−4 in summer (EDT), so the gap is 12 or 11 hours. The tool works it out for the date you pick.
What is the difference between EST and PST?
PST is 3 hours behind EST. When it is 12:00 EST it is 09:00 PST.
What is 16:9?
A width to height ratio of 16 to 9, the standard for most TVs and video, for example 1920×1080.
How is a ratio simplified?
Divide the width and height by their greatest common divisor. 1920×1080 divided by 120 gives 16:9. The tool does this automatically.
Which units can I convert?
Length, weight, temperature, volume, speed and area, including Thai units such as rai, ngan and square wah.
How do I convert temperature?
Multiply Celsius by 9/5 and add 32 for Fahrenheit, so 25°C is 77°F. The tool does it for you.
Does it work on my phone?
Yes. It runs in the browser on iPhone and Android, with no app to install.
Where do my files go? Are they stored?
Nowhere. Files are processed only in your browser, are never uploaded to a server, and are gone when you close the page.
