What Does the Ångström Unit Mean in Wavelengths?

[homestar]

I'm sorry if this is the wrong forum but in a problem I was given wavelength with the unit as an A with a circle above it, can anyone tell me what this means and how I can get it into more familiar terms (meters, for example)?

found it in windows character map Å

I wish I could delete this thread because I just found out the unit is an Angstrom, 10^-10 meters

It's an Ångström, which is equal to 1x10^-10 metres.
