Question 1

What units are used in chemical engineering?

Accepted Answer

Chemical engineers commonly use SI units (Pa, kg, m, K) and US customary units (psi, lb, ft, °F). This converter supports all common engineering units across 15 categories.

Question 2

How do I convert pressure units?

Accepted Answer

Common conversions: 1 atm = 101.325 kPa = 14.696 psi = 760 mmHg = 1.01325 bar. Select pressure category and enter value to convert between any units.

Question 3

How do I convert temperature units?

Accepted Answer

Temperature requires offset conversion: °C = K - 273.15, °F = 1.8×°C + 32, °R = 1.8×K. This calculator handles all temperature conversions correctly.

Question 4

What flow rate units are common in process engineering?

Accepted Answer

Common flow units: m³/h, L/min, GPM (US gallons per minute), CFM (cubic feet per minute). Mass flow uses kg/h, lb/h, or tonne/h depending on region.
