Seer (Ser)

What is a seer (ser)?

The seer (ser) equals about 933 grams, or eighty tola (close to one kilogram).

Origin of the seer (ser)

From Hindi/Urdu 'ser', a major pre-metric trade weight.

Where it is used

Historical grain, milk, and produce trade across South Asia.

When and where it was developed

Standardized in British India; aligned near 1 kg after metrication.

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.

Seer (Ser) 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 seers (ser) and planck mass:

1 seer = 4.286764e+7 mP
1 mP = 2.332762e-8 seer

To convert seers (ser) to planck mass, multiply the value in seers (ser) by 4.286764e+7. To reverse, multiply planck mass by 2.332762e-8.

How to use this converter

Type a value into the calculator. The result in planck mass updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Planck Mass to Seer (Ser) converter for the reverse direction.

Step-by-step: convert seers (ser) to planck mass

  1. Write down the value in seers (ser) (seer).
  2. Multiply that value by the factor 4.286764e+7.
  3. The product is the equivalent value in planck mass (mP).
  4. To reverse, multiply the planck mass value by 2.332762e-8.

Worked examples

Example 1 — Convert 1 seer to mP:
1 × 4.286764e+7 = 4.286764e+7 mP

Example 2 — Convert 100 seer to mP:
100 × 4.286764e+7 = 4.286764e+9 mP

Real-world example — Human-scale to atomic dimensions

One seer (ser) equals one billion planck mass — the canonical metric conversion bridging everyday objects and atomic-scale features in physics, chemistry, and electronics.

1 seer × 4.286764e+7 = 4.286764e+7 mP

Real-world example — Meter to nanoscale

One seer (ser) equals one billion planck mass. Physics curricula use this conversion to teach orders of magnitude when introducing the electromagnetic spectrum.

1 seer × 4.286764e+7 = 4.286764e+7 mP
