What does foot water (4°C) measure?

It measures pressure exerted by a 1-foot column of pure water at 4°C, commonly used for hydraulic head and low-pressure indications.

Why is centimeter mercury (0°C) used in measurements?

It is a manometric pressure unit based on mercury column height at 0°C, often used in laboratories and precision instrumentation.

Are there any safety concerns using this conversion?

Yes, mercury is toxic, so precautions are necessary when handling or using equipment calibrated with mercury-based units.
