Full API documentation

Explanation

Convert US cups of simple syrup (1:1) to grams using a density reference of 1.23 g/mL. With the US cup fixed at 236.588 mL, that gives 291 grams per cup for this ingredient.

That is useful for syrups and sweeteners used in bars, desserts, and beverage prep where sticky volume measures still need reliable weight equivalents. Simple syrup (1:1) can vary with sugar concentration and temperature, so the converter keeps one syrup-style reference instead of switching between generic sweetener charts.

Method & Density Basis

Density basis: 1.23 g/mL (anchored to US cup 236.588 mL and US fl oz 29.57 mL).
Applied factor: 1 Cup = 291 Grams.
Consistency rule: mirror pages invert the same per-liquid constants so forward and reverse directions remain aligned.

Methodology

Simple syrup (1:1) density evidence

Simple syrup (1:1) uses 1.23 g/mL in this dataset, which is 23.0% heavier by volume than the 1 g/mL water reference. Evidence status: medium-confidence. Source basis: 1:1 simple syrup density estimate.

Brand formulation, alcohol or sugar concentration, carbonation, and serving temperature can change the weight of a measured volume. Use this value as a documented reference rather than a producer specification.
