Neutron Mass

What is a neutron mass?

The neutron rest mass is about 1.6749E-27 kg, slightly more than the proton.

Origin of the neutron mass

The mass of the neutron, the neutral nucleon.

Where it is used

Nuclear physics and reactor science.

When and where it was developed

Determined after James Chadwick discovered the neutron in 1932.

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.

Neutron Mass 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 neutron mass and rattis:

1 mn = 1.378542e-23 ratti
1 ratti = 7.254041e+22 mn

To convert neutron mass to rattis, multiply the value in neutron mass by 1.378542e-23. To reverse, multiply rattis by 7.254041e+22.

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 Neutron Mass converter for the reverse direction.

Step-by-step: convert neutron mass to rattis

  1. Write down the value in neutron mass (mn).
  2. Multiply that value by the factor 1.378542e-23.
  3. The product is the equivalent value in rattis (ratti).
  4. To reverse, multiply the ratti value by 7.254041e+22.

Worked examples

Example 1 — Convert 1 mn to ratti:
1 × 1.378542e-23 = 1.378542e-23 ratti

Example 2 — Convert 100 mn to ratti:
100 × 1.378542e-23 = 1.378542e-21 ratti

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

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

1000 mn × 1.378542e-23 = 1.378542e-20 ratti

Real-world example — Sub-visible-light wavelength

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

500 mn × 1.378542e-23 = 6.89271e-21 ratti
