Inconsistency in block units

[Jimster]

Yesterday I added a watermeter to Domoticz, how the usage is shown is a little bit ugly, like this: 123l (see image below). Is there a way to change te l to liters?
I noticed that how the different units are shown is inconsistent.
Some show Watt, some W, some with a space between the value and some without. My temp meters show 21.1 C, and the thermostat shows 19,5°C with the degree sign in between and with a comma. Maybe this can be made more consistent in future.
I think with the space in between looks best. I don't think decimals are needed when the unit is Watt. for kWh 2 decimals is ok.
See the different blocks I have:
