ft/s to m/s
m/s to ft/s
Step-by-Step Conversion Process
- Identify your starting value: Determine the speed in feet per second that you need to convert.
- Apply the conversion factor: Multiply the ft/s value by 0.3048 to obtain the equivalent in metres per second.
- Round appropriately: For most practical purposes, rounding to 2-4 decimal places provides sufficient accuracy.
- Verify the result: Check that your answer makes sense – m/s values should be approximately 30% of the original ft/s value.
Worked Example
Problem: Convert 25 ft/s to m/s
Solution:
- Starting value: 25 ft/s
- Apply formula: 25 × 0.3048 = 7.62 m/s
- Result: 25 ft/s = 7.62 m/s

Understanding the Units
Feet per Second (ft/s)
Feet per second represents the distance travelled in feet over one second. This unit remains common in the United States and in specific engineering fields, particularly aerospace and aviation. Historical usage stems from imperial measurement systems, where feet provided a familiar reference for distance. In aviation, feet per second frequently describes climb rates, descent rates, and wind speeds.
Metres per Second (m/s)
Metres per second serves as the SI (International System of Units) standard for velocity. Scientific research, physics laboratories, and most global engineering projects adopt m/s as the primary speed unit. The metric system’s decimal structure simplifies conversions and reduces errors in complex scenarios. UK road signs typically display miles per hour, but scientific and engineering contexts favour m/s for precision and international compatibility.
Regional Differences
The UK officially transitioned to metric units for most scientific and technical applications, yet imperial units persist in specific contexts such as road signage (miles per hour). Engineering projects in the UK commonly work in metres per second to align with European and international standards. Aviation retains feet per second for altitude rates and certain performance metrics due to global industry conventions established decades ago.
Frequently Asked Questions
How do I convert 60 ft/s to m/s?
Multiply 60 by 0.3048 to get 18.288 m/s. This represents a moderately fast speed, roughly equivalent to 65 km/h or 41 mph.
Why does the conversion factor equal 0.3048?
The conversion factor derives from the international agreement that one foot equals exactly 0.3048 metres. This standardisation occurred in 1959 when English-speaking nations established the international foot definition.
Which unit is more commonly used in UK scientific research?
Metres per second dominates UK scientific research, academic publications, and engineering projects. The metric system’s adoption across Europe and its status as the SI standard make m/s the preferred choice for precision and international collaboration.
How fast is the speed of sound in both units?
At sea level and 20°C, the speed of sound measures approximately 1,125 ft/s or 343 m/s. This value varies with temperature, humidity, and altitude, but these figures serve as standard references in physics and engineering.
Can I convert ft/s to other speed units?
Absolutely. From ft/s, you can convert to mph (multiply by 0.681818), km/h (multiply by 1.09728), or knots (multiply by 0.592484). However, converting to m/s first often simplifies subsequent conversions to other metric units.
What speed in ft/s equals 1 m/s?
One metre per second equals approximately 3.28084 ft/s. This represents a moderate walking pace, roughly 3.6 km/h or 2.24 mph.
How accurate should my conversions be?
For everyday purposes, 2-3 decimal places suffice. Scientific work may require 4-5 decimal places for precision. Engineering specifications typically dictate the required accuracy level based on the application’s tolerance requirements.
Do wind speeds use ft/s or m/s in the UK?
UK meteorological reports typically present wind speeds in miles per hour for public communication, but m/s appears in scientific weather data and aviation meteorology. International meteorological standards favour m/s for consistency across borders.
