Two quick lookups every slow cooker owner needs: convert a stovetop or oven recipe into slow cooker Low/High hours, and check the safe (and shred-ready) internal temperature for whatever protein is in the pot.
Pick the range that matches how long the original stovetop or oven recipe takes to cook through (not prep time — just the active heat time on the stove or in the oven).
This is the standard slow cooker conversion guideline used across manufacturer manuals (roughly: Low runs about half the temperature intensity of High, so it takes roughly 2× as long). Treat it as a starting point, not a guarantee — always cook to a safe internal temperature, not a clock. Liquid-heavy dishes (soups, chilis) usually need less added liquid than the original recipe since a slow cooker doesn't reduce liquid the way a stovetop does.
USDA minimum safe internal temperatures, plus the higher "shred-ready" range slow cooker recipes often target for pulled meat (collagen needs extra time and heat beyond the safety minimum to break down into that fall-apart texture).
Always verify with an instant-read or probe thermometer inserted into the thickest part of the meat, away from bone. A slow cooker's ambient temperature is not a substitute for checking internal temperature directly.
Most recipe conversions online are eyeballed. This calculator uses the same rule of thumb tested by slow cooker manufacturers and food-safety extension offices: Low heat runs roughly 190–200°F inside the pot, High runs roughly 250–300°F, and both eventually reach the same doneness — Low just takes longer. That's why you can leave a Low-set roast for a 9-hour workday and come home to dinner instead of a dry, overcooked pot.
