Slow cooker time conversion calculator
A slow cooker runs at around 90 degrees Celsius on low and 100 on high, so times stretch by a factor of six to eight against a conventional recipe.

Show the working
- Conventional cooking time = 90
- Low setting multiplier = 7
- High setting multiplier = 3.5
- Liquid reduction = 30
- Liquid in the recipe = 500
- Low, in minutes = 90 * 7 = 630
- High, in minutes = 90 * 3.5 = 315
- Time on low = 630 * 60 = 37 800
- Time on high = 315 * 60 = 18 900
- Liquid to use = 500 * (1 - 30/100) = 350
- High as a fraction of low = 7 > 0 ? 3.5 / 7 : 0 = 0.5
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- slow cooker time = conventional time x setting multiplier
A sealed slow cooker loses almost no liquid, so recipes adapted from the oven need roughly a third less.
Multipliers vary by machine. Treat the first attempt as a calibration run.
