Units explained

Metric / SI

Nanogram

What is a nanogram?

A nanogram (ng) equals 10^-12 kilogram.

Origin of the nanogram

From the SI prefix 'nano-' (from Greek 'nanos', dwarf).

Where it is used

Molecular biology, forensics, and toxicology.

When and where it was developed

The nano- prefix entered the SI in 1960.

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.

Nanogram 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 nanograms and rattis:

1 ng = 8.230453e-9 ratti
1 ratti = 1.215e+8 ng

To convert nanograms to rattis, multiply the value in nanograms by 8.230453e-9. To reverse, multiply rattis by 1.215e+8.

How to use this converter

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

Step-by-step: convert nanograms to rattis

  1. Write down the value in nanograms (ng).
  2. Multiply that value by the factor 8.230453e-9.
  3. The product is the equivalent value in rattis (ratti).
  4. To reverse, multiply the ratti value by 1.215e+8.

Worked examples

Example 1 — Convert 1 ng to ratti:
1 × 8.230453e-9 = 8.230453e-9 ratti

Example 2 — Convert 100 ng to ratti:
100 × 8.230453e-9 = 8.230453e-7 ratti

Real-world example — Sub-visible-light wavelength

500 nanograms (the green-yellow visible band) equals 0.5 rattis — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.

500 ng × 8.230453e-9 = 4.115226e-6 ratti

Real-world example — Spanning sub-micron to micron scale

Crossing from nanograms to rattis is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 nanograms translates to a much more compact value in rattis that fits the scale of biological cells and process nodes.

1000 ng × 8.230453e-9 = 8.230453e-6 ratti
