Units explained

Metric / SI

Picogram

What is a picogram?

A picogram (pg) equals 10^-15 kilogram.

Origin of the picogram

From the SI prefix 'pico-' (from Spanish 'pico', a small quantity).

Where it is used

Single-cell biology and ultratrace chemical analysis.

When and where it was developed

The pico- prefix entered the SI in 1960.

Troy & Apothecary

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.

Picogram to Point (1/100 carat) conversion formula

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

1 pg = 5e-10 pt

1 pt = 2e+9 pg

To convert picograms to points (1/100 carat), multiply the value in picograms by 5e-10. To reverse, multiply points (1/100 carat) by 2e+9.

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 Picogram converter for the reverse direction.

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

Write down the value in picograms (pg).
Multiply that value by the factor 5e-10.
The product is the equivalent value in points (1/100 carat) (pt).
To reverse, multiply the point (1/100 carat) value by 2e+9.

Worked examples

Example 1 — Convert 1 pg to pt:
1 × 5e-10 = 5e-10 pt

Example 2 — Convert 100 pg to pt:
100 × 5e-10 = 5e-8 pt

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

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

1000 pg × 5e-10 = 5e-7 pt

Real-world example — Sub-visible-light wavelength

500 picograms (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 pg × 5e-10 = 2.5e-7 pt
