PPM / mg/m³ conversion with PID correction factors
This tool helps with PID detection and gas concentration conversion. Follow this short guide.
Enter the name, molecular formula or CAS number in the search field. The local database returns results instantly; if PubChem is enabled, unknown substances are looked up online.
The three values show the response factor for 11.7 eV, 10.6 eV and 10.0 eV lamps. The color coding (green/yellow/red) indicates how well the gas can be detected.
Enter the molecular weight and the measured value. Use the arrow button to switch between PPM → mg/m³ and mg/m³ → PPM. Temperature and pressure can be adjusted under "Advanced Settings".
Based on the PID values and gas properties, suitable measuring devices are suggested. Click on a device name to go to the product page.
The calculations, conversions and results provided in this application ("PID Gas Search") are intended solely for information and orientation purposes. Despite careful development and verification, no warranty is given for the correctness, completeness, timeliness or suitability of the provided content for a specific purpose.
The application does not replace any professional assessment, standard-compliant testing, or documentation required by authorities or experts. In particular, the results do not constitute a binding statement about gas concentration, detectability or the suitability of measuring devices.
Responsibility for interpreting and using the calculated values lies solely with the user. Decisions made on the basis of this application are at the user's own risk.
The operator/developer assumes no liability for material or immaterial damages, directly or indirectly arising from the use or non-use of the provided information, unless caused by intent or gross negligence.
It is the user's responsibility to independently observe and comply with the applicable standards, guidelines, legal regulations and test requirements (e.g. relevant DIN, EN or ISO standards).
By using the application, the user agrees to these terms.
Präzise Umrechnung für die Dichtheitsmessung
Welcome to the Leak Rate Converter. Below is an overview of the formulas and functions used.
Converts various leak rate units (mbar·l/s, scc/s, g/a, oz/yr, ppm) into each other.
PPM formula (depends on suction flow):
PPM = (Leak rate cm³/s / Suction flow cm³/s) × 1,000,000
Mass leak rates (g/a) use the ideal gas law: q = (m_dot × R × T) / M
Calculates the equivalent leak rate under different pressure or gas conditions for laminar flow (Hagen-Poiseuille).
Formula: Q2 = Q1 × (η1 / η2) × [ (P2_in² - P2_out²) / (P1_in² - P1_out²) ]
Determines the required test leak rate based on standardized tightness classes (e.g. water-tight). For SF6 systems (0.1 % loss/year):
Q_Ref = (System volume × Fill pressure × 0.001) / 31,536,000 s
Converts a physical pressure drop into a volumetric leak rate.
Formula: dv/dt = (V / P_atm) × (dp/dt)
Note: For the unit mbar·l/s, atmospheric pressure is not included (pure pV throughput).
The calculations, conversions and results provided in this application ("Leak Rate Converter") are intended solely for information and orientation purposes. Despite careful development and verification, no warranty is given for the correctness, completeness, timeliness or suitability of the provided content for a specific purpose.
