One of the oldest weight units of the Indian subcontinent, later standardized.

Metric / SI

Quintal (metric)

What is a quintal (metric)?

The metric quintal (q) equals 100 kilograms.

Origin of the quintal (metric)

From Latin 'centenarius' (hundredweight) via Arabic 'qintar'.

Where it is used

Agriculture across India, Europe, and Latin America for grain and produce.

When and where it was developed

Fixed at 100 kg with the spread of the metric system in the 19th century.

Ratti to Quintal (metric) 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 quintals (metric):

1 ratti = 1.215e-6 q
1 q = 823045.2674897119 ratti

To convert rattis to quintals (metric), multiply the value in rattis by 1.215e-6. To reverse, multiply quintals (metric) by 823045.2674897119.

Step-by-step: convert rattis to quintals (metric)

  1. Write down the value in rattis (ratti).
  2. Multiply that value by the factor 1.215e-6.
  3. The product is the equivalent value in quintals (metric) (q).
  4. To reverse, multiply the quintal (metric) value by 823045.2674897119.

Worked examples

Example 1 — Convert 1 ratti to q:
1 × 1.215e-6 = 1.215e-6 q

Example 2 — Convert 100 ratti to q:
100 × 1.215e-6 = 0.0001215 q

Real-world example — Hair-width scale measurements

A 70-ratti measurement (about the diameter of a human hair) is the kind of value materials engineers regularly express in adjacent micro-scale units like quintals (metric) for direct comparison across supplier datasheets.

70 ratti × 1.215e-6 = 8.505e-5 q

Real-world example — Paper and film thicknesses

At the thickness of office paper (roughly 3 rattis), converting between sub-millimeter units is routine for packaging and printing buyers comparing quotes from metric and US suppliers.

3 ratti × 1.215e-6 = 3.645e-6 q

Real-world example — Plastic-film thickness alternates

A 150-ratti plastic film converts cleanly to quintals (metric) — useful for packaging buyers reconciling supplier datasheets across metric and US measurement systems.

150 ratti × 1.215e-6 = 0.00018225 q
