@@ -140,6 +140,10 @@ The `format` option supports the following values:
 | datetime | `timestamp` | Convert timestamp value to date and time |
 | brightness | `number` | Convert brightness value to percentage |
 | duration | `number` | Convert number of seconds to duration (`5:38:50`) |
+| duration-m | `number` | Convert number of milliseconds to duration (`5:38:50`) |
+| invert | `number` | Convert number from positive to negative or vice versa |
+| kilo | `number` | Divide number value by 1000 (ex. `1500 W` -> `1.5 kW`) |
+| position | `number` | Reverses a position percentage (ex. `70%` open -> `30%` closed) |
 | precision<0-9> | `number` | Set decimal precision of number value (`precision3` -> `18.123`) |
