I bought one of the LC meters you are talking about.  I have had it for a couple months and it is great.  I have two other different kinds, I bought earlier and I hate them.  won't measure most of what I hook them up to.  But this one is great.  I am so happy with it I am going to give it a new home inside a nice utility box.

What is the smallest inductance and capacitance it will measure?

What is the smallest inductance and capacitance it will measure?

The minimum resolution: 0.01 pF
* Inductance measuring range: 0.001 uH - 100mH
* Big inductance measuring range: 0.001 mH - 100H

Thanks. That is a great deal.

0.001 microHenry, that is, one nanoHy? Sorry, I don't believe it. The display might display 1.000 milliHenry at the low range but this is false precision.

What is the inductance of one inch, straight,  of #27 magnet wire?

It is over 26 nanoHy, more than 26 times your instrument's stated lower limit.

So you are telling me that instrument can measure accurately..... the inductance of two millimeters of wire.

It is over 26 nanoHy,

This guy claims that for helixes of large pitch, a coiled wire has less inductance than a straight wire!
Don't take my word for it - read it.
