Billable hours, man-day conversions, engagement totals — precise to the minute, formatted for the ledger.
Time billing lives and dies on the h:mm → decimal conversion: 38h 45m must invoice as 38.75, and a "day" in your engagement model is 8 hours, not 24. TCalc handles both — instant decimal output, and custom converters that know a working day from a calendar day.
Total a team's week in one expression and read it back in whichever unit the report wants.
Engagement total as invoice-ready decimal.
Duration to total hours in one tap.
Three staff days totalled.
Hours back to days — and with custom converters, a day can be 8h.
Divide minutes by 60: 38h 45m = 38.75 hours. TCalc shows any duration as decimal hours with one tap on the output format.
Yes — the built-in conversion treats a day as 24h (36h = 1.5D), and custom converters let you define a working day as 8h so 1 week = 40 hours, matching how engagements are actually billed.
Yes — TCalc keeps full precision (down to seconds and beyond); 6 minutes is 0.1h and totals never drift from rounding.
