Verified usage

Quantity

✓ from ansys.units import Quantity

✗ from ansys.units.units import Quantity

Old submodule path deprecated; use top-level import.

Basic usage of Quantity for unit conversions and arithmetic.

from ansys.units import Quantity # Create a quantity with value and units q = Quantity(10.0, 'm') print(q) # 10.0 m # Convert to different units q_ft = q.to('ft') print(q_ft) # 32.8084 ft # Perform arithmetic q2 = Quantity(5.0, 's') print(q / q2) # 2.0 m/s # Check compatibility print(q.compatible('km')) # True print(q.compatible('kg')) # False

Debug

Known issues

gotchaQuantity multiplication/division may unexpectedly change units if not careful with order of operations.

fix

Use parentheses or explicit conversion with .to() before arithmetic.

affects: all

deprecatedImporting from ansys.units.units or ansys.units.quantity is deprecated. Use directly from ansys.units.

fix

Change import to 'from ansys.units import Quantity'.

affects: >=0.10

breakingIn version 0.11.0, the Quantity constructor changed to accept unit string as second positional argument (previously unit keyword).

fix

Use positional argument: Quantity(10.0, 'm') instead of Quantity(10.0, units='m').

affects: 0.11.0

Errors

Common errors & fixes

AttributeError: module 'ansys.units' has no attribute 'Quantity'

Installed version <0.10 where Quantity was in submodule.

fix

Upgrade to >=0.10 and use 'from ansys.units import Quantity'.

ValueError: Unknown unit: 'm/s'

Unit string may be case-sensitive or composite not recognized.

fix

Use 'm*s^-1' or 'meter/second' (check set_units).
