The viscosity of water at 20°C is approximately 1 centipoise, making it a standard for comparison. To accurately check liquid thickness, it's crucial to understand that 'thickness' refers to the scientific property of viscosity, which can be measured using both simple at-home techniques and advanced laboratory instruments.

According to the International Dysphagia Diet Standardisation Initiative (IDDSI), a standardized global framework, the primary IDDSI test used to measure the thickness of drinks is the IDDSI Flow Test. This simple, accessible method helps healthcare professionals ensure that modified liquids are safe for individuals with dysphagia.

Viscosity, the property that defines a liquid's resistance to flow, is a critical factor in human nutrition, affecting everything from food texture and consumer acceptance to safety for those with swallowing disorders. A high-viscosity liquid, like honey, resists flow, while a low-viscosity liquid, like water, flows freely.
