Verified SI Standard

➡️ Convert nm to au

Value in AU = Value in nm × 6.684587e-21

To convert any quantity from nm to au, multiply the quantity by the constant conversion factor 6.684587e-21.

⬅️ Convert au to nm (Inverse)

Value in nm = Value in AU × 1.495979e+20

To reverse the operation, multiply your au figure by 1.495979e+20 (or divide by 6.684587e-21).

🔢 Step-by-Step Calculation Procedure:

Identify the starting value in nm (nm).
Apply the exact linear conversion factor: 1 nm = 6.684587e-21 AU.
Multiply the input value by 6.684587e-21 to obtain the exact measurement in au (AU).
Verify precision against standard BIPM / NIST SP 811 statutory guidelines.
