Work out story point to hours instantly with clear inputs, formula shown and shareable results.
Story points are deliberately unitless, but a conversion is sometimes needed for budgeting. Deriving hours per point from the team's own velocity and capacity — using six productive hours per person-day rather than eight — keeps the conversion grounded in observed reality.
Sprint capacity
Capacity hours = Team size x Sprint days x 6 productive hours
Hours per point
Hours per point = Sprint capacity hours / Team velocity
For planning within the team, yes. For an external budget conversation it is often unavoidable — just never use the conversion to hold the team to hourly estimates.
Because meetings, code review, support and context switching consume the rest. Teams that plan on eight consistently overcommit.
