To update a given item
Suppose the item to be updated is line {1}.
- Click line {1} to select it.
…the item's value is echoed in the input field, and the item's units are shown in the units dropdown, together with any compatible units which TABULA knows about. - Edit/replace the data in the input field.
Examples of acceptable inputs to update the given item
Suppose line {1} is currently: 1 m
- 6 m
—changes: 1 m to: 6 m - 6
—changes 1 m to: 6 m
if you don't want to change the units, then m is superfluous. - [ft]
—changes: 1 m to: 3.281 ft
i.e. 1 metre, converted to feet - 18 [ft]
—replaces the entire quantity (i.e. both value and units) with: 18 ft . - 18 [kg]
—leaves the line unaltered and displays the error message:
>>> incompatible units: [m][kg]
How to create a new line showing any desired quantity
Suppose you want your new line (say {2}) to show the quantity: 2.34 ft/s
- Click the New Line tool.
…The new line will appear like this: 1 * - Enter in the input field: 2.34 [ft/s]
If you omit brackets […] round the units, then TABULA takes: 2.34 ft/s to represent a quantity, which is to be preserved as a quantity and converted to SI units (the default units for that given quantity).
TABULA does not signal: >>> incompatible units: … because the quasi-unit [*] is compatible with any units.
