The EMT Conduit calculator estimates the time to install, the length installed and the weight of Electrical Metallic Tubing (EMT Conduit) 

Cable and Conduit Installation Calculators

The Math / Science

EMT stands for Electrical Metallic Tubing (aka thin-wall tubing).  EMT is often used as a lower cost solution to galvanized rigid conduit (GRC).  EMT is not threaded but can be used with threaded fittings via the use of clamps.  EMT is typically made of steel.

The relationship between length of conduit, level of difficulty, size of EMT and the time to install comes from industry standard numbers.  The following table is the basis of this calculator.

The relationship between length of conduit, size of EMT and the weight comes from industry standard numbers.  The following table is the basis of the weight estimates in this calculator and it shows the mass / weight value of the EMT per hundred feet length.
