How does this convert regular recipe times to slow cooker times?

It applies conversion ratios between oven/stovetop times and slow cooker low/high settings.

What's the ratio between low and high settings?

Low typically takes roughly twice as long as high for the same dish.

Why can't I just guess slow cooker time from oven time?

Slow cookers use much lower, consistent heat over longer periods, so conversion isn't linear.

What Is the Slow Cooker Time Converter?

The Slow Cooker Time Converter translates a conventional oven or stovetop cooking time into the equivalent Low or High slow cooker setting, using standard conversion ranges used by slow cooker manufacturers.

Formula Used

Conversion based on standard ranges:
15-30 min → Low 4-6 hr / High 1.5-2.5 hr
35-45 min → Low 6-8 hr / High 3-4 hr
50 min+ → Low 8-10 hr / High 4-6 hr

These are standard manufacturer conversion guidelines, not a precise formula — actual times vary by dish, quantity, and slow cooker model, so check doneness rather than relying on time alone.

How to Use This Calculator

Enter the original recipe's stovetop or oven cooking time in minutes.
Click Calculate to see the equivalent Low and High slow cooker time ranges.

Worked Example

A recipe that takes 30 minutes on the stovetop converts to about 4-6 hours on Low, or 1.5-2.5 hours on High in a slow cooker.
