Convert pounds to teaspoons or teaspoons to pounds for common ingredients using density, with options for ounces, grams, kilograms, cups, mL, and liters.

Ingredient presets are illustrative, editable density assumptions. Results vary with temperature, composition and packing; match the spoon size to your recipe.

Assumptions Assumptions
  • Conversions are weight-to-volume and require a density (ฯ) in g/mL.
  • Listed densities are illustrative, editable assumptions; temperature, packing (e.g., scooped vs. spooned flour), composition and brand can change results.
  • Unit standards: 1 lb = 453.59237 g; 1 US tsp โ‰ˆ 4.92892 mL; 1 US tbsp โ‰ˆ 14.7868 mL; 1 US cup โ‰ˆ 236.588 mL. The calculator uses the full US customary factors.
  • 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 โ€œCustom densityโ€ to enter your own value.
  • Mass โ€” enter a mass in lb, oz, g, or kg.
  • Volume 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. The displayed formula rounds the US teaspoon factor; the calculator uses 4.92892159375 mL per US teaspoon.

tsp = (453.59237) / (4.92892) (lb) / (ฯ)
  • 1 pound (lb) = 453.59237 grams (g)
  • 1 US teaspoon (tsp) โ‰ˆ 4.92892 milliliters (mL)
  • 1 US tablespoon (tbsp) โ‰ˆ 14.7868 mL
  • 1 US cup โ‰ˆ 236.588 mL
  • ฯ (density) must be in g/mL; results vary by ingredient and packing.

* Assumes water at room temperature (ฯ โ‰ˆ 1.00 g/mL). Other ingredients require their own density.

How do you convert pounds to teaspoons? Multiply pounds by 453.59237 to get grams, divide by density (g/mL) to get mL, then divide by 4.92892 to get US teaspoons.

Example Problem

Convert 1.5 lb of granulated sugar to US teaspoons (ฯ โ‰ˆ 0.85 g/mL).

Use the formula: tsp = (lb ร— 453.59237) รท (ฯ ร— 4.92892).

tsp = (1.5 ร— 453.59237) รท (0.85 ร— 4.92892) โ‰ˆ 162.4 tsp
