Story points vs hours
The conversion table is the failure mode. If you can convert points to hours, you're estimating hours.
If you can convert points to hours, you're estimating hours.
Story points and hours are not different units of the same thing. Hours measure duration — how long something will take you. Points measure relative effort — how big this is compared to the reference story everyone already shipped. They're different axes. The moment you write "1 point = 4 hours" on the wiki, you've re-cast every estimation conversation as a duration argument, and you've thrown away the relative-effort property the technique exists to give you.
The reason teams reach for the conversion is real: someone outside the team needs a date, and points don't have units. The fix isn't a conversion table; it's velocity. Velocity already maps points to time at the team level — points-per-sprint × number-of-sprints gives you a date that respects the team's actual delivery rate, not a fictional rate.
Why points exist at all
The team that estimates in hours is two estimates: the estimate the senior person believes, and the estimate the junior person believes after rounding up to look responsible. Hidden cards plus relative effort dodges both. Points let the team agree on "this is bigger than that one we shipped" without agreeing on "this will take me four hours."
What good looks like
A team using points well doesn't talk about hours during the session. They talk about the reference story, the comparable work they've shipped, and the unknowns. The number that comes out is a relative-effort signal that the team — and only the team — can convert into a date through their own velocity.
Burn the conversion table. Project from velocity instead.
Common questions
How many hours is 3 story points?
There's no fixed answer, and that's the point. Story points measure relative effort, not duration — 3 points is 'a bit bigger than our reference story,' which takes different teams different amounts of time. Convert at the team level through velocity, never per story.
Is 1 story point equal to 1 day?
No. A story point isn't a unit of time at all. If your team has settled into '1 point = 1 day,' you're estimating in days with a Fibonacci coat of paint — and you've lost the relative-effort signal points exist to give you.
Is a story point 8 hours?
No. Any fixed points-to-hours rate recreates time estimation with extra steps. Two stories sized the same in points can take different amounts of time; a conversion table pretends they can't.
Why use story points instead of hours?
Because the team can agree 'this is bigger than that' without agreeing 'this will take me four hours.' Hidden cards plus relative sizing dodges anchoring and the seniority bias hour estimates invite — and velocity still gives you a date when you need one.
Can you convert story points to hours?
Only at the team level, and only after the fact: points completed per sprint (velocity) maps points to calendar time for that specific team. A standing per-story 'X points = Y hours' table is the failure mode — burn it.
