In India, gemstone buyers frequently encounter the term “Ratti” when shopping for gems. Traditionally, “Ratti” is a standard Indian unit for measuring mass. Its origins trace back to the Sanskrit word Raktika, referenced in classical Ayurvedic texts for weighing small objects. In India, Ratti is often used as a counterpart to the “Carat,” a unit more commonly recognized internationally.

There are two main types of Ratti: Sunari Ratti, primarily used by goldsmiths to measure metals, and Pakki Ratti, which is more relevant to gemstone measurements. Gemstone dealers and astrologers often prefer the Pakki Ratti unit, especially when following Vedic guidelines for astrological recommendations.

Because gemstones today are mostly weighed in Carats, this difference in units can sometimes confuse buyers who are used to the Ratti measurement. To simplify things, we’ve included a convenient Ratti-to-Carat converter below. This ensures accurate conversions and helps avoid misunderstandings. Additionally, you can refer to the conversion tables provided, which show the ratios between Ratti, Carat, Milligram, and Gram measurements.

For reference:

• 1 Carat = 1.11 Ratti

• 1 Ratti = 0.90 Carat

• 1 Carat = 0.20 Gram

• 1 Carat = 200 Milligrams

Disclaimer: Gemrishi advises customers to purchase gemstones measured in “Carats.” Although Ratti is widely used regionally, it may sometimes lead to inconsistencies in understanding measurements.
