9 - Is this a test answer or do you just want to know for a project you're doing? Take a look at NEC chapter 9 - tables 4 and 5 (in the 2005 edition at least)
1/2 inch is 1.27 cm
There are 12.7 millimeters in half an inch.
There are two half-inches in one inch.
Approximately 9-10 18AWG wires can fit in a 2 inch conduit, depending on the type of insulation on the wires and the specific requirements of the installation. It's always advisable to consult the National Electrical Code (NEC) or local regulations for specific guidelines on conduit fill capacity.

The National Electrical Code (NEC) provides guidelines for conduit fill calculations. For half-inch PVC conduit, you can typically fit about 6 to 7 number 12 THHN wires. However, the exact number may vary depending on factors such as the specific type of insulation and the installation conditions, so it's always best to refer to NEC tables for precise calculations.

The number of 12-gauge wires that can fit in a three-quarter inch conduit depends on the type of conduit and the specific application. Generally, for a three-quarter inch EMT conduit, you can fit about 9 to 10 number 12 wires, following the National Electrical Code (NEC) guidelines for conduit fill. It's essential to consider derating factors and any additional requirements based on the installation conditions. Always consult the NEC or a qualified electrician for precise calculations.
For a 90-degree bend on 1.5-inch conduit, you typically deduct 10 inches from the total length of the conduit. This deduction accounts for the bend's radius and allows for proper installation. Always refer to local codes and guidelines, as requirements may vary.

9-10, but the conduit may not exceed a certain length, or a certain voltage in order for you to "legally" do it. Many applications allow for conduit fill ratio's that exceed the standards of the NEC ( National Electrical Code) and most of them are short (less than 24") "chases" between control devices mounted in listed Junction boxes for that purpose. It is not advisable to fill a conduit more than the NEC allows for purposes of heat dissipation.
