Whenever you store a value that has a unit in a variable, config option or CLI switch, include the unit in the name. So:
maxRequestSize
=>maxRequestSizeBytes
elapsedTime
=>elapsedSeconds
cacheSize
=>cacheSizeMB
chargingTime
=>chargingTimeHours
fileSizeLimit
=>fileSizeLimitGB
temperatureThreshold
=>temperatureThresholdCelsius
diskSpace
=>diskSpaceTerabytes
flightAltitude
=>flightAltitudeFeet
monitorRefreshRate
=>monitorRefreshRateHz
serverResponseTimeout
=>serverResponseTimeoutMs
connectionSpeed
=>connectionSpeedMbps
EDIT: I know it’s better to use types to represent units. Please don’t write yet another comment about it. You can find my response to that point here: https://programming.dev/comment/219329
I like how in Nim you can create a type and then overload default operators to support custom types (operators are just functions with 2 arguments in Nim), in example: you can do Hours + Seconds or kilometers * miles, etc. It feels very organic and not like a “hack”.
