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.

Force / Engineering

Kilogram-force square second/meter

What is a kilogram-force square second/meter?

The kilogram-force second-squared per meter (the hyl or TME) is about 9.807 kg.

Origin of the kilogram-force square second/meter

The mass unit of the metric gravitational (technical) system.

Where it is used

Older continental European engineering practice.

When and where it was developed

Used in the metric technical system before SI adoption.

Ratti to Kilogram-force square second/meter 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 kilogram-force square second/meters:

1 ratti = 1.238955e-5 hyl
1 hyl = 80713.1687242798 ratti

Worked examples

Example 1 — Convert 1 ratti to hyl:
1 × 1.238955e-5 = 1.238955e-5 hyl

Example 2 — Convert 100 ratti to hyl:
100 × 1.238955e-5 = 0.0012389552 hyl

Real-world example — Macro-scale buildup

A million rattis equals exactly one kilogram-force square second/meter — the conversion that bridges microscale features and macroscale objects in microfluidic, biomedical, and semiconductor packaging design.

1000000 ratti × 1.238955e-5 = 12.3895519877 hyl

Real-world example — Quarter-meter measurement reference

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

250000 ratti × 1.238955e-5 = 3.0973879969 hyl

Real-world example — From microscopic to macroscopic

A million rattis equals exactly one kilogram-force square second/meter. This kind of conversion appears in microfluidics, where total channel length is given in kilogram-force square second/meters but feature widths are in rattis.

1000000 ratti × 1.238955e-5 = 12.3895519877 hyl
