How is the fluid deficit calculated from dehydration percentage?

Explanation:
Fluid deficit is the amount of fluid missing from the body due to dehydration. The calculation uses body weight in kilograms multiplied by the dehydration fraction—the percent dehydration expressed as a decimal. In other words, deficit (liters) = weight (kg) × (percent dehydration as a decimal). If you’re given a percentage, convert it by dividing by 100 (for example, 5% becomes 0.05). So a 10 kg child with 5% dehydration has a deficit of 10 × 0.05 = 0.5 L. Using the percent as a whole number (5) would give an unrealistically large value, and using pounds or dividing by the weight would not reflect the true fluid loss.
