About Converting Technical atmospheres to Atmospheres
Technical atmosphere and Atmosphere both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Technical atmosphere is kilogram-force per square centimeter, and a standard atmosphere is exactly 101,325 pascals.
Formula
atmospheres = technical atmospheres × 0.967841105354
This factor comes from each unit's defined relationship to the category's base unit: 1 technical atmosphere equals 98066.5 base units, and 1 atmosphere equals 101325 base units, so dividing one by the other gives the direct technical atmosphere-to-atmosphere factor of 0.967841105354.
Simple example
1 at × 0.9678411054 = 0.9678411054 atm
1 technical atmosphere = 0.9678411054 atmospheres.
Real-world example
100 at × 0.9678411054 = 96.78411054 atm
100 technical atmospheres = 96.78411054 atmospheres.

Understanding the Technical atmosphere (at)
Technical atmosphere is kilogram-force per square centimeter.
Understanding the Atmosphere
Atmosphere (atm) measures pressure. Defined as exactly 101,325 pascals, originally based on the average atmospheric pressure at mean sea level. It is classified as a non-SI unit accepted for use with the SI.
Where it's used: Widely used internationally in chemistry, meteorology, and diving/aviation contexts alongside the pascal and bar
Uses of the Atmosphere today
- Chemistry (standard conditions are often defined at 1 atm)
- Diving and aviation pressure references
- General reference for everyday atmospheric pressure

Frequently asked questions
How many atmospheres are in 1 technical atmosphere?
1 technical atmosphere equals 0.9678411054 atmospheres, using the exact defined conversion factor rather than an estimate.
How do I convert technical atmosphere to atmosphere?
Multiply the technical atmosphere value by 0.9678411054. The converter above does this instantly to whatever precision you set.
How do I convert atmosphere back to technical atmosphere?
Use the reverse factor: 1 atmosphere equals 1.033227453 technical atmospheres. You can also use the swap control in the converter above to flip the direction instantly.
What is a technical atmosphere?
Technical atmosphere (at) is a unit of engineering.
What is a atmosphere?
Atmosphere (atm) measures pressure. Defined as exactly 101,325 pascals, originally based on the average atmospheric pressure at mean sea level. It is classified as a non-SI unit accepted for use with the SI.
Is the technical atmosphere to atmosphere conversion exact?
Yes. Defined as exactly 101,325 pascals, originally based on the average atmospheric pressure at mean sea level. That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
