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.

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.

Worked examples

Example 1 — Convert 1 hg to ratti:
1 × 823.0452674897 = 823.0452674897 ratti

Example 2 — Convert 100 hg to ratti:
100 × 823.0452674897 = 82304.5267489712 ratti

Real-world example — Sub-meter precision

A 0.001-hectogram (1 mm) tolerance equals 1,000 rattis — useful for surface-finish specs, where macro-scale dimensions are given in the larger unit but feature roughness in the smaller.

0.001 hg × 823.0452674897 = 0.8230452675 ratti

Real-world example — Macro-to-micro scale comparison

2 hectograms of measurement converts to a very large number in rattis — useful in materials science when comparing bulk-sample dimensions to feature-level surface specs.

2 hg × 823.0452674897 = 1646.0905349794 ratti

Real-world example — Macroscopic to microscopic

One hectogram equals a million rattis. Optical engineers calculating coherence length compare macro-scale path lengths with micro-scale wavelength differences using exactly this conversion.

1 hg × 823.0452674897 = 823.0452674897 ratti
