i don't know that there is any "measurements", but here are some ways i use it:
1) first i separate it into at least two different bottles b/c the one i keep in the shower i dillute by at least half. i find it to be a bit drying on the skin, so diluting it helps and makes it last longer
2) i use it full strength in the sink for dishes, but i only put in maybe a TBSP?, don't know really, i just squirt some in and go about washing...no suds
3) i don't use it for laundry...
