Raceway Fill Calculator - Cerrowire
https://www.cerrowire.com/products/resources/tables-calculators/raceway-fill-calculator/
Raceway Fill Calculator. The purpose of this calculator is to determine one of two values: the maximum number of conductors (wires) that can fit into a given type and size of raceway, or the minimum trade size of a raceway that is required for a given combination of conductors (wires). All calculations are based on the National Electrical Code®.

Size Raceways for a Successful Installation - EC&M
https://www.ecmweb.com/content/article/20891686/size-raceways-for-a-successful-installation
The answer is (d), 39. This answer comes directly from Table C7 in Annex C. Sizing a raceway using Tables 4 and 5. When the conductors to be installed aren't the same size and/or they don't have the same insulation type, use these steps to properly size the raceway.

This program calculates the number of same size conductors using the .8 roundoff method. In the Auto Mode this program limits the fill to 40 per cent for over 2 conductors, 31 per cent for only two conductors, and 53 percent for one conductor. …
Fill Er Up - EC&M
https://www.ecmweb.com/national-electrical-code/code-basics/article/20892946/fill-er-up
You just locate the table for the raceway type you're using, find the conductor type on that table, and look up the size and quantity. For example, if you want to know how many 14 RHH conductors (without cover) you can install in trade size 1 EMT, just take a look at Annex C, Table C.1. The answer is 16 conductors.
Maximum Number of Electrical Wires Allowed in Conduit
https://www.thespruce.com/number-of-electrical-wires-for-conduit-1152860
Electrical conduit, whether it be rigid metal (EMT), rigid plastic (PVC), or flexible metal (FMC), is limited as regards the maximum number of electrical wires that can be run inside the conduit. This rating, called conduit fill capacity, is specified by the National Electrical Code and followed by most local codes, which serve as the governing ...
