Convert pounds to teaspoons or teaspoons to pounds for common ingredients using density, with options for ounces, grams, kilograms, cups, mL, and liters.
Assumptions Assumptions
- Conversions are weight-to-volume and require a density (ฯ) in g/mL.
- Listed densities are approximate at room temperature; packing (e.g., scooped vs. spooned flour) and brand can change results.
- Unit standards: 1 lb = 453.59237 g; 1 US tsp = 4.92892 mL; 1 US tbsp = 14.7868 mL; 1 US cup = 236.588 mL.
- UK/Imperial teaspoon and cup sizes are not supported.
When to Use This Calculator
- Translating a recipe that lists ingredients by weight (lb/oz) to kitchen measures (tsp/tbsp/cups).
- Estimating storage volume from bulk weight of dry goods or liquids.
- Converting small lab or DIY project amounts where density is known or can be estimated.
Input Definitions
- Ingredient โ sets density ฯ (g/mL); choose โCustom densityโ to enter your own value.
- Pounds โ enter a weight in lb, oz, g, or kg.
- Teaspoons โ enter a volume in US tsp, tbsp, cup, mL, or L.
- Formulas โ tsp = (lb ร 453.59237) รท (ฯ ร 4.92892); lb = (tsp ร 4.92892 ร ฯ) รท 453.59237.
Lbs to Teaspoons Formula
The following formula converts pounds to teaspoons using density ฯ in grams per milliliter (g/mL); rearrange to convert teaspoons back to pounds.
- 1 pound (lb) = 453.59237 grams (g)
- 1 US teaspoon (tsp) = 4.92892 milliliters (mL)
- 1 US tablespoon (tbsp) = 14.7868 mL
- 1 US cup = 236.588 mL
- ฯ (density) must be in g/mL; results vary by ingredient and packing.
