Convert Astronomical Units to Angstroms

To convert astronomical units to angstroms, the value is multiplied by the exact conversion factor 1.4960e+21 — that is, 1 astronomical units = 1.4960e+21 angstroms. This tool applies that reference factor so results are precise.

1. 1

   Step 1

   Enter the value to convert.

2. 2

   Step 2

   Click the "Calculate" button to see the result instantly.

3. 3

   Step 3

   You can re-run the calculation with different values anytime.

4. 4

   Step 4

   Review the breakdown: the result repeats the exact factor (1.4960e+21), so the Astronomical Units → Angstroms arithmetic is verifiable line by line.

5. 5

   Step 5

   Change the value and compare scenarios: entering 10 then 100 in astronomical units shows the angstroms output scaling exactly by 1.4960e+21.

• 1

  This page converts Astronomical Units to Angstroms using the exact reference factor 1.4960e+21. That is the standard figure, so the results here match reference tables rather than rounded approximations.

• 2

  Round only the final result: keep full precision while converting Astronomical Units to Angstroms and round once at the end, because rounding every intermediate step lets drift accumulate until the final figure drifts from its true value.

• 3

  Enter plain decimal numbers without thousand separators: a comma can be read as a decimal mark in some locales and silently change the magnitude of the Astronomical Units value you meant to convert to Angstroms.

• The exact factor for Astronomical Units → Angstroms carries 7 significant digits (1.4960e+21); rounding it early to 1.5000e+21 drifts a 1,000 astronomical units input by about 4.0213e+21 angstroms. Round only the final displayed answer.

• Order-of-magnitude check: 1 Astronomical Unit = 1.4960e+21 Angstrom exactly, so type 1 first — a wildly different angstroms figure means a stray comma, wrong field, or flipped direction before you convert real values.
