When and where it was developed

Adopted in assay laboratories using the long ton.

Indian / South Asian

Ratti

What is a ratti?

The ratti equals about 0.1215 gram, the smallest traditional South Asian weight.

Origin of the ratti

Based on the seed of the Gunja plant (Abrus precatorius), or 'raktika' in Sanskrit.

Where it is used

Gemstones and gold in Indian and South Asian jewelry.

When and where it was developed

One of the oldest weight units of the Indian subcontinent, later standardized.

Ton (assay) (UK) to Ratti conversion formula

Note: this conversion uses a generally accepted modern value. Historical and regional definitions of this unit varied across times and places.

The relationship between tons (assay) (uk) and rattis:

1 AT = 268.861454321 ratti
1 ratti = 0.0037193878 AT

Worked examples

Example 1 — Convert 1 AT to ratti:
1 × 268.861454321 = 268.861454321 ratti

Example 2 — Convert 100 AT to ratti:
100 × 268.861454321 = 26886.1454320988 ratti

Real-world example — Adjacent metric sub-units

One ton (assay) (uk) equals 1,000 rattis. Engineers move between these scales constantly: PCB feature sizes in the larger unit, wire-bond diameters in the smaller.

1 AT × 268.861454321 = 268.861454321 ratti

Real-world example — Adjacent small-scale precision

One ton (assay) (uk) equals 1,000 rattis — the standard sub-millimeter precision conversion that materials engineers use whenever they switch between bulk material thickness specs (larger unit) and surface-finish characteristics (smaller unit).

1 AT × 268.861454321 = 268.861454321 ratti
