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.

Metric / SI

Hectogram

What is a hectogram?

A hectogram (hg) equals 0.1 kilogram, or 100 grams.

Origin of the hectogram

From the SI prefix 'hecto-' (from Greek 'hekaton', hundred).

Where it is used

Common in continental European food retail, especially Italy ('etto').

When and where it was developed

The hecto- prefix dates to the original metric system of 1795.

Ratti to Hectogram 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 rattis and hectograms:

1 ratti = 0.001215 hg
1 hg = 823.0452674897 ratti

To convert rattis to hectograms, multiply the value in rattis by 0.001215. To reverse, multiply hectograms by 823.0452674897.

How to use this converter

Type a value into the calculator. The result in hectograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Hectogram to Ratti converter for the reverse direction.

Step-by-step: convert rattis to hectograms

  1. Write down the value in rattis (ratti).
  2. Multiply that value by the factor 0.001215.
  3. The product is the equivalent value in hectograms (hg).
  4. To reverse, multiply the hectogram value by 823.0452674897.

Worked examples

Example 1 — Convert 1 ratti to hg:
1 × 0.001215 = 0.001215 hg

Example 2 — Convert 100 ratti to hg:
100 × 0.001215 = 0.1215 hg

Real-world example — Macro-scale buildup

A million rattis equals exactly one hectogram — the conversion that bridges microscale features and macroscale objects in microfluidic, biomedical, and semiconductor packaging design.

1000000 ratti × 0.001215 = 1215 hg

Real-world example — Quarter-meter measurement reference

A 250,000-ratti length equals 0.25 hectograms — useful for comparing supply-chain spec sheets where some lengths are quoted in the smaller unit and some in the larger.

250000 ratti × 0.001215 = 303.75 hg

Real-world example — From microscopic to macroscopic

A million rattis equals exactly one hectogram. This kind of conversion appears in microfluidics, where total channel length is given in hectograms but feature widths are in rattis.

1000000 ratti × 0.001215 = 1215 hg
