About Converting Technical atmospheres to mmHgs
Technical atmosphere and mmHg 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 millimeters of mercury at standard gravity.
Formula
mmhgs = technical atmospheres × 735.559135277
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 mmhg equals 133.322387415 base units, so dividing one by the other gives the direct technical atmosphere-to-mmhg factor of 735.559135277.
Simple example
1 at × 735.5591353 = 735.5591353 mmHg
1 technical atmosphere = 735.5591353 mmhgs.
Real-world example
100 at × 735.5591353 = 73,555.91353 mmHg
100 technical atmospheres = 73,555.91353 mmhgs.

Frequently asked questions
How many mmhgs are in 1 technical atmosphere?
1 technical atmosphere equals 735.5591353 mmhgs, using the exact defined conversion factor rather than an estimate.
How do I convert technical atmosphere to mmhg?
Multiply the technical atmosphere value by 735.5591353. The converter above does this instantly to whatever precision you set.
How do I convert mmhg back to technical atmosphere?
Use the reverse factor: 1 mmhg equals 0.00135951 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 mmhg?
mmHg (mmHg) is a unit of engineering.
Is the technical atmosphere to mmhg conversion exact?
Yes. Both technical atmosphere and mmhg are defined by fixed standards rather than physical artifacts, so the factor of 735.5591353 used above is exact to as many digits as you choose to display.
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.
