On a schematic I have, some resistors read as R16, 0.025R, 3W. Some read as R60, 33R. I guessed that R16 or R60 are the labels, and 3W is the power. But what does 0.025R or 30R mean? Google search did not help much. Thanks.

In this context "R" means \$\Omega\$.

It really just substitutes for the decimal point and tells you the multiplier. You'll also see inductors marked 1R0 for 1.0\$\mu\$H, and resistances given as 4K7 or 10K0 for 4700\$\Omega\$ and 10,000 \$\Omega\$.

So the resistor with ID R16 is a 0.025 Ohm resistor and the resistor with ID R60 is a 33 Ohm resistor.

    \$\begingroup\$ Some other resistors read as 33K. Are they 33 kOhms? \$\endgroup\$ – Adeel Apr 22 '15 at 14:41

    \$\begingroup\$ Yes, they are 33K ohms. \$\endgroup\$ – Spehro Pefhany Apr 22 '15 at 14:42
  • \$\begingroup\$ @Chu If it starts with "R" in this context, that is the reference designator. This is generally why the value of the resistors don't contain "R"s. \$\endgroup\$ – ACD Apr 22 '15 at 15:57
  • \$\begingroup\$ R60 is 33 ohms, yes? \$\endgroup\$ – EM Fields Apr 22 '15 at 17:51
  • \$\begingroup\$ @EMFields Yes, thanks, some weird editing there- no doubt my fault. \$\endgroup\$ – Spehro Pefhany Apr 22 '15 at 17:55
