Freezer tools

The pages here answer the question a food card cannot: when. How long a thaw will take, how much of a power cut your freezer has left, whether the thing you just defrosted can go back in. Each one runs on published USDA, FDA and CDC guidance and shows its working.

How these work

The calculator can only be as honest as its inputs

Every figure behind these tools is published guidance, and each tool cites it in full. The per-pound thawing rates come from the USDA's turkey and package guidance rather than one universal formula, so a thaw shows a range and asks you to check the middle of the food rather than trusting a clock. The outage windows are the CDC's closed-door estimates, which are about how long the appliance holds cold — not a promise about what is inside it. Where guidance stops, the tool stops and tells you to look.

Two rules sit behind all of them. A freezer at 0 °F (−18 °C) makes food safe indefinitely, so a storage window is a quality window and nobody is in danger for eating something older than its best-by month. And an appliance that has been above 40 °F for long enough is a different situation entirely — that is the one place where the answer changes from "worse" to "don't". Both are set out once in the freezer safety standard.

Not a tool

Looking for a specific food?

The calculators here are about time and events. If you want a plain answer for one food — whether it freezes at all, how to pack it, how to bring it back — the food cards have 2,000+ of them, and the search finds any of them in a word or two. Try ricotta, avocado or cooked rice if you want to see the shape of one.
