Introduction
In fluid mechanics and engineering, viscosity is a crucial property that determines a fluid’s resistance to flow. The kinematic viscosity of a fluid is often measured in Stokes (St) or its derivatives, such as Gigastokes (GSt). However, in some regions, particularly the United States, the preferred unit for kinematic viscosity is square foot per second (ft²/s).
This article provides a detailed guide on converting 71.48 Gigastokes (GSt) to square foot per second (ft²/s), including the formula, step-by-step calculations, and practical applications.
Units
1. What is a Gigastokes (GSt)?
- Gigastokes (GSt) is a unit of kinematic viscosity in the metric system.
- 1 GSt = 1 × 10⁹ Stokes (St)
- It is commonly used in industrial and scientific applications where high viscosity values are involved.
2. What is Square Foot per Second (ft²/s)?
- Square foot per second (ft²/s) is the imperial unit of kinematic viscosity.
- It measures how easily a fluid flows under gravity, considering its density and dynamic viscosity.
Conversion Formula: Gigastokes to Square Foot per Second
The conversion between Gigastokes (GSt) and square foot per second (ft²/s) is based on the following relationship:1 Stokes (St)=1.07639×10−3 ft²/s1Stokes (St)=1.07639×10−3ft²/s

- Used in oil & gas, automotive lubrication, and aerospace engineering where viscosity measurements are critical.
- Scientific Research & Data Analysis
- Ensures compatibility between different measurement systems in academic and experimental studies.
Practical Applications
1. Oil & Petroleum Industry
- High-viscosity fluids like crude oil are often measured in GSt, but U.S. refineries may require ft²/s for processing.
2. Aerospace & Automotive Lubricants
- Engine oils and hydraulic fluids must meet precise viscosity standards, requiring accurate unit conversions.
3. Chemical Manufacturing
- Polymer solutions and industrial chemicals often have viscosity values in GSt, but equipment may be calibrated in ft²/s.
FAQs
Q1. How do you convert Gigastokes to ft²/s?
- Multiply the value in GSt by 1.07639 × 10⁶ to get ft²/s.
Q2. What is the difference between kinematic and dynamic viscosity?
- Kinematic viscosity (St, ft²/s) considers fluid density, while dynamic viscosity (Pa·s, Poise) measures resistance independently.
Q3. Is Stokes or ft²/s more commonly used?
- Stokes is more common in metric-based countries, while ft²/s is used in the U.S. and some imperial-based industries.
