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.

Scientific / Atomic

Planck Mass

What is a planck mass?

The Planck mass equals about 2.18E-8 kg, formed from the constants h-bar, c, and G.

Origin of the planck mass

Introduced by Max Planck in 1899 as part of a system of natural units.

Where it is used

Theoretical physics and quantum-gravity research.

When and where it was developed

Defined by Planck in 1899 from fundamental constants.

Ratti to Planck Mass 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 planck mass:

1 ratti = 5581.8184324049 mP
1 mP = 0.0001791531 ratti

To convert rattis to planck mass, multiply the value in rattis by 5581.8184324049. To reverse, multiply planck mass by 0.0001791531.

Step-by-step: convert rattis to planck mass

  1. Write down the value in rattis (ratti).
  2. Multiply that value by the factor 5581.8184324049.
  3. The product is the equivalent value in planck mass (mP).
  4. To reverse, multiply the planck mass value by 0.0001791531.

Worked examples

Example 1 — Convert 1 ratti to mP:
1 × 5581.8184324049 = 5581.8184324049 mP

Example 2 — Convert 100 ratti to mP:
100 × 5581.8184324049 = 558181.8432404868 mP

Real-world example — Infrared to visible-spectrum mapping

A 10-ratti thermal infrared wavelength corresponds to a much larger number in planck mass, the unit favoured for ultraviolet and visible-light specifications.

10 ratti × 5581.8184324049 = 55818.1843240487 mP

Real-world example — Mid-micron to nanometer

3 rattis equals 3,000 planck mass — useful when relating mid-infrared wavelengths (typically quoted in microns) to nanometer-scale visible-light wavelength tables.

3 ratti × 5581.8184324049 = 16745.4552972146 mP

Real-world example — From microns to sub-micron features

One ratti equals one thousand planck mass — the conversion semiconductor designers do constantly when comparing mask feature dimensions to actual transistor gate lengths.

1 ratti × 5581.8184324049 = 5581.8184324049 mP
