3" EMT Conduit Weight(w): The calculator returns the estimated weight in pounds. However this can be automatically converted to compatible units via the pull-down menu.
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, size of EMT and the weight comes from industry standard numbers. The table above is the basis of this calculator and it shows the mass / weight value of the EMT per hundred feet length.
EMT Conduit Calculators
- Rolling Offset (run and Travel): This computes the travel length of pipe or conduit between two angle fixtures and the linear advancement (run) in a rolling offset.
- EMT Conduit Installation Time: This estimates the amount of time needed to install Electrical Metallic Tubing (EMT Conduit) based on the length of the conduit, the Level of Difficulty and the size of the conduit.
- EMT Conduit Length: This estimates the length of Electrical Metallic Tubing (EMT Conduit) that can be installed based on the Level of Difficulty, the size of the conduit and the amount of time allocated.
- EMT Conduit Weight: This estimates the total weight of Electrical Metallic Tubing (EMT Conduit) based on the size of the conduit (S) and the length (L).
