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.

Biblical / Ancient

Gerah (Biblical Hebrew)

What is a gerah (biblical hebrew)?

The gerah was the smallest Hebrew weight, about 0.57 gram (one-twentieth of a shekel).

Origin of the gerah (biblical hebrew)

From a Hebrew word for a small grain or bean.

Where it is used

Ancient Israelite metrology.

When and where it was developed

Part of the smallest divisions of the biblical shekel.

Planck Mass to Gerah (Biblical Hebrew) 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 planck mass and gerahs (biblical hebrew):

1 mP = 3.818789e-5 gerah
1 gerah = 26186.3086952327 mP

To convert planck mass to gerahs (biblical hebrew), multiply the value in planck mass by 3.818789e-5. To reverse, multiply gerahs (biblical hebrew) by 26186.3086952327.

How to use this converter

Type a value into the calculator. The result in gerahs (biblical hebrew) updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Gerah (Biblical Hebrew) to Planck Mass converter for the reverse direction.

Step-by-step: convert planck mass to gerahs (biblical hebrew)

  1. Write down the value in planck mass (mP).
  2. Multiply that value by the factor 3.818789e-5.
  3. The product is the equivalent value in gerahs (biblical hebrew) (gerah).
  4. To reverse, multiply the gerah (biblical hebrew) value by 26186.3086952327.

Worked examples

Example 1 — Convert 1 mP to gerah:
1 × 3.818789e-5 = 3.818789e-5 gerah

Example 2 — Convert 100 mP to gerah:
100 × 3.818789e-5 = 0.0038187895 gerah

Real-world example — Sub-visible-light wavelength

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

500 mP × 3.818789e-5 = 0.0190939474 gerah

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

Crossing from planck mass to gerahs (biblical hebrew) is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 planck mass translates to a much more compact value in gerahs (biblical hebrew) that fits the scale of biological cells and process nodes.

1000 mP × 3.818789e-5 = 0.0381878947 gerah
