Units explained
Dekagram
A dekagram (dag) equals 0.01 kilogram, or 10 grams.
From the SI prefix 'deka-' (from Greek 'deka', ten).
Widely used in Central and Eastern European cooking and shops (dag/dkg).
Part of the original metric system introduced in 1795.
Attogram
An attogram (ag) equals 10^-21 kilogram.
From the SI prefix 'atto-' (from Danish 'atten', eighteen).
Frontier nanoscience and single-molecule mass detection.
The atto- prefix was adopted by the CGPM in 1975.
Dekagram to Attogram conversion formula
The relationship between dekagrams and attograms:
To convert dekagrams to attograms, multiply the value in dekagrams by 1e+19. To reverse, multiply attograms by 1e-19.
How to use this converter
Type a value into the calculator. The result in attograms updates as you type. Tap a quick value, copy the result with one click, or use the swap arrow to jump straight to the Attogram to Dekagram converter for the reverse direction.
Step-by-step: convert dekagrams to attograms
- Write down the value in dekagrams (dag).
- Multiply that value by the factor 1e+19.
- The product is the equivalent value in attograms (ag).
- To reverse, multiply the attogram value by 1e-19.
Worked examples
Example 1 — Convert 1 dag to ag:
1 × 1e+19 = 1e+19 ag
Example 2 — Convert 100 dag to ag:
100 × 1e+19 = 1e+21 ag
Real-world example — Centimeter to wavelength scale
One dekagram equals 10 million attograms. Physics curricula use this kind of conversion to relate everyday measurements to atomic and optical scales.
1 dag × 1e+19 = 1e+19 ag
Real-world example — Small-scale to atomic-scale
One dekagram equals 10 million attograms — useful for physics curricula that relate everyday measurements to atomic and optical scales.
1 dag × 1e+19 = 1e+19 ag
