Units explained

Metric / SI

Femtogram

What is a femtogram?

A femtogram (fg) equals 10^-18 kilogram.

Origin of the femtogram

From the SI prefix 'femto-' (from Danish/Norwegian 'femten', fifteen).

Where it is used

Nanotechnology and high-sensitivity mass spectrometry.

When and where it was developed

The femto- prefix was adopted by the CGPM in 1975.

Metric / SI

Decigram

What is a decigram?

A decigram (dg) equals 0.0001 kilogram, or 0.1 gram.

Origin of the decigram

From the SI prefix 'deci-' (from Latin 'decimus', tenth).

Where it is used

Occasional laboratory and pharmacy use.

When and where it was developed

Part of the original metric system of 1795.

Femtogram to Decigram conversion formula

The relationship between femtograms and decigrams:

1 fg = 1e-14 dg
1 dg = 1e+14 fg

To convert femtograms to decigrams, multiply the value in femtograms by 1e-14. To reverse, multiply decigrams by 1e+14.

How to use this converter

Type a value into the calculator. The result in decigrams updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Decigram to Femtogram converter for the reverse direction.

Step-by-step: convert femtograms to decigrams

  1. Write down the value in femtograms (fg).
  2. Multiply that value by the factor 1e-14.
  3. The product is the equivalent value in decigrams (dg).
  4. To reverse, multiply the decigram value by 1e+14.

Worked examples

Example 1 — Convert 1 fg to dg:
1 × 1e-14 = 1e-14 dg

Example 2 — Convert 100 fg to dg:
100 × 1e-14 = 1e-12 dg

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

Crossing from femtograms to decigrams is the everyday workflow of microscopy and semiconductor engineering — a measurement of 1000 femtograms translates to a much more compact value in decigrams that fits the scale of biological cells and process nodes.

1000 fg × 1e-14 = 1e-11 dg

Real-world example — Sub-visible-light wavelength

500 femtograms (the green-yellow visible band) equals 0.5 decigrams — the canonical conversion in optics between wavelength specifications and micron-scale lens-coating thicknesses.

500 fg × 1e-14 = 5e-12 dg

Frequently asked questions

How many decigrams is 1 femtogram?
1 femtogram equals 1e-14 decigram.
How do I convert femtograms to decigrams?
Multiply the value in femtograms by 1e-14 to get decigrams.
How do I convert decigrams back to femtograms?
Multiply the value in decigrams by 1e+14, or use the Decigram to Femtogram converter.
How many decigrams is 100 femtograms?
100 femtograms equals 1e-12 decigrams, because 100 × 1e-14 = 1e-12.
