Invert is fully unit-aware across the platform. Every metric, property, and formula carries its unit, and you can convert between compatible units at any time.
Supported units
Invert covers a wide range of units used in bioprocessing:
Temperature: °C, °F, K
Mass: g, kg, mg
Volume: L, mL, µL
Concentration: g/L, g/mL, mg/L, mg/dL
Pressure: bar, psi, mmHg
Flow rate: L/h, L/min, mL/h, mL/min, SLPM, m³/h, m³/min
Mass flow: g/h, g/min
Amount of substance: mol, mmol, µmol
Molar flow: mol/h, mol/min, mmol/h, mmol/min
Volumetric rate: mol/L/h, mol/L/min, mmol/L/h, mmol/L/min
Length: cm, µm
Area: cm²
Energy / Torque: kJ, mNm
Viscosity: cP
Conductivity: µS, mS/cm
Agitation: RPM
Cell count: CFU/kg, CFU/g, CFU/mg
Time: h, min
You can also type units manually—Invert recognizes hundreds of standard SI, imperial, and scientific units.
Converting units
Click the unit next to any metric in charts or tables
Select a compatible unit (only valid conversions are shown)
Values, axes, and tooltips update instantly
Conversions are display-only and apply per metric per view—your raw data stays unchanged.
Molar conversions
If a molar mass is defined, you can convert between mass and mole units:
g/L ⇄ mol/L, mmol/L, µmol/L, M, mM
g ⇄ mol, mmol, µmol
Set molar mass (in g/mol) in the Library to unlock these options.
Bioprocess-specific units
Invert includes domain-specific units like:
RPM (agitation)
vvm (gas flow per liquid volume)
pH (dimensionless)
CFU / BCFU (cell counts)
E6_cells (millions of cells)
SLPM / NLPM (gas flow)
cP (viscosity)
Flexible input
Invert automatically normalizes common variations:
Deg C,C→ °CKg,kgs→ kgml→ mLrpm→ RPMPSI→ psicells→ count
No need to clean unit labels before importing.
Built-in constants
Available directly in formulas:
Gas constant (R): 8.31451 Pa·m³/(K·mol)
O₂: 31.999 g/mol
CO₂: 44.01 g/mol
N₂: 28.0134 g/mol
Ar: 39.948 g/mol
NH₄: 18.03846 g/mol
Glucose: 180.156 g/mol
Time axis in charts
You can switch time display independently:

Tips
Unit suggestions are always dimensionally compatible
Conversions never modify underlying data
You can type custom units directly
