Units explained

Metric / SI

Nanogram

What is a nanogram?

A nanogram (ng) equals 10^-12 kilogram.

Origin of the nanogram

From the SI prefix 'nano-' (from Greek 'nanos', dwarf).

Where it is used

Molecular biology, forensics, and toxicology.

When and where it was developed

The nano- prefix entered the SI in 1960.

Point (1/100 carat)

What is a point (1/100 carat)?

A point equals one-hundredth of a carat, or 2 milligrams.

Origin of the point (1/100 carat)

A subdivision of the metric carat for very small stones.

Where it is used

The diamond trade, for sub-carat stones.

When and where it was developed

Adopted alongside the metric carat in the 20th-century gem trade.

Nanogram to Point (1/100 carat) conversion formula

The relationship between nanograms and points (1/100 carat):

1 ng = 5e-7 pt
1 pt = 2000000 ng

To convert nanograms to points (1/100 carat), multiply the value in nanograms by 5e-7. To reverse, multiply points (1/100 carat) by 2000000.

How to use this converter

Type a value into the calculator. The result in points (1/100 carat) updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Point (1/100 carat) to Nanogram converter for the reverse direction.

Step-by-step: convert nanograms to points (1/100 carat)

  1. Write down the value in nanograms (ng).
  2. Multiply that value by the factor 5e-7.
  3. The product is the equivalent value in points (1/100 carat) (pt).
  4. To reverse, multiply the point (1/100 carat) value by 2000000.

Worked examples

Example 1 — Convert 1 ng to pt:
1 × 5e-7 = 5e-7 pt

Example 2 — Convert 100 ng to pt:
100 × 5e-7 = 5e-5 pt

Real-world example — Sub-visible-light wavelength

500 nanograms (the green-yellow visible band) equals 0.5 points (1/100 carat) — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.

500 ng × 5e-7 = 0.00025 pt

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

Crossing from nanograms to points (1/100 carat) is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 nanograms translates to a much more compact value in points (1/100 carat) that fits the scale of biological cells and process nodes.

1000 ng × 5e-7 = 0.0005 pt
