Convert foot water (4°C) to ton-force (long)/square foot
Please provide values below to convert foot water (4°C) [ftAq] to ton-force (long)/square foot [tonf (UK)/ft^2], or Convert ton-force (long)/square foot to foot water (4°C).
How to Convert Foot Water (4°c) to Ton-Force (Long)/square Foot
1 ftAq = 0.0278688148319135 tonf (UK)/ft^2
Example: convert 15 ftAq to tonf (UK)/ft^2:
15 ftAq = 15 × 0.0278688148319135 tonf (UK)/ft^2 = 0.418032222478702 tonf (UK)/ft^2

Foot Water (4°c)
Foot water (4°C), symbol ftAq, is a unit of pressure representing the height of a water column at 4°C that exerts a specific pressure.
History/Origin
The foot water (4°C) has been used historically in engineering and scientific contexts to measure pressure, especially in water-related applications, as an alternative to other pressure units like inches of water or meters of water. Its usage dates back to traditional measurements in hydraulic and civil engineering.
Current Use
Today, foot water (4°C) is primarily used in specialized fields such as hydrology, water management, and engineering to measure low pressures, particularly in systems involving water flow and pressure head calculations.
Ton-Force (Long)/square Foot
Ton-force (long) per square foot is a unit of pressure representing the force exerted by one long ton (2,240 pounds) distributed over one square foot.
History/Origin
This unit originated in the UK as a practical measure for engineering and industrial applications, combining the long ton (used primarily in the UK) with square foot to measure pressure in contexts such as structural and mechanical engineering.
Current Use
Today, ton-force per square foot is rarely used in modern engineering, having been largely replaced by SI units like pascals. It may still appear in historical data, specialized fields, or regional contexts within the UK.
