Convert Every Kind of Unit, Including Thai Ones: Rai, Ngan, Square Wa, Gold Baht and Tang

Land in Thailand is measured in rai, ngan and square wa, while international data uses square metres or hectares. Converting by hand is error-prone; this tool does it in one place.

Pick a unit and only the matching ones appear

Enter a number and choose the source unit. The target list then shows only units of the same kind; choose feet and you are left with length units. Type to search for a unit, tap a number to copy it, or tap a unit name to make it the target.

Coverage

• 15 categories and over 140 units.
• Thai units: rai, ngan, square wa, wa, sok, gold baht, tang.

A caution

Some units have more than one definition by country, such as the gallon (US and UK). Check you have chosen the kind you mean.
