How many carats are in one Ratti?

In the Indian gem trade one Ratti is commonly taken as 0.91 carat (about 0.182 g). The older Sunari or jeweller's Ratti is about 0.1215 g, or roughly 0.61 carat. Always ask your seller which standard they use.

How do I calculate Ratti for my body weight?

A popular rule of thumb is one Ratti for every 10 kg of body weight — 60 kg suggests about 6 Ratti. It is a traditional guideline only; astrologers may suggest a different weight for your chart.

Is Ratti the same as carat?

No. Carat is the international unit (0.2 g). Ratti is a traditional Indian unit originally based on the weight of a Gunja seed, and its value differs by standard.

Does a heavier gemstone give stronger results?

Tradition associates a minimum weight with effectiveness, but no gemstone or weight guarantees any outcome. Quality, genuineness and your own practice matter more than size.

What is a Ratti?

Ratti is a traditional Indian unit of weight, originally the weight of a single Gunja (Abrus precatorius) seed. It is still used to describe gemstone weights in Jyotish. Because two standards exist, a "5 Ratti" stone can mean about 4.55 carat (gem-trade) or about 3.04 carat (Sunari) — so always confirm which one a seller uses.
