Seers to Kilograms (seer to kg)

1 seer equals 0.933104304 kilograms exactly.

1 seer = 0.933104304 kilograms

How to convert seers to kilograms

To convert seers to kilograms, multiply the number of seers by 0.933104304. This factor is exact. To go the other way, multiply kilograms by 1.071691552 (rounded).

kilograms = seers × 0.933104304

Example: 10 seers = 9.33104304 kilograms.

About these units

Seer (seer)

Indian subcontinentTraditional unit (still used in some regions)

80 tolas, about 933 g. A traditional South Asian measure of grain and other goods.

Over large parts of Asia the seer served as the everyday grocer's weight, used for rice, wheat, ghee and similar goods, and in some places also as a measure of volume. Under the Mughals a seer was 30 dams and 40 seers made a maund. Each British presidency later kept its own version. Bengal reckoned the seer as 16 chitaks of 5 tolas, which is 80 tolas.

The government seer of British India comes to about 0.93310 kg, the figure used here, and the same value survives in Pakistan, Nepal and Aden. After independence India's Standards of Weights and Measures Act of 1956 set the seer at 1.25 kg instead, and then metric weights replaced it. Other values are far apart: Afghanistan uses about 7.066 kg, Iran has a metric seer of 75 g and a sihr of 160 g, and in Sri Lanka the seer is a capacity of about 1.06 L. The word seer must therefore always be tied to a place and date.

1 seer = 0.933104304 kilograms (exactly).

Kilogram (kg)

Metric (SI)Current unit

The SI base unit of mass. Since 2019 it is defined by fixing the value of the Planck constant, replacing the old platinum-iridium cylinder in Paris.

Oddly for a base unit, the kilogram began life as a derived one. In 1793 revolutionary France defined the grave as the mass of one litre of water, and a decree of 1795 then replaced it with the kilogramme, a name built from the Greek khilioi (a thousand) and gramma, a Late Latin word for a small weight. In 1799 a platinum cylinder, the Kilogramme des Archives, became the physical standard, matching a cubic decimetre of water at its densest, around 4 degrees Celsius. In 1889 the metric community adopted a platinum-iridium cylinder made in 1879, the International Prototype of the Kilogram, nicknamed Le Grand K.

The kilogram is still the only SI base unit with a prefix in its name. Because SI forbids stacked prefixes, a millionth of a kilogram is a milligram rather than a microkilogram, so every mass prefix is attached to the gram. Calibrating every national standard against one object in a vault near Paris meant that all of them drifted relative to it, so in November 2018 member states voted to tie the kilogram to a fixed value of the Planck constant. The change took effect on 20 May 2019. Day to day nothing shifted, but the definition no longer depends on a single piece of metal.

The kilogram is the reference unit for weight & mass on this site.
