The definition was actually for 4 °C, the point at which water is most dense. At 20 °C the density of water is about 0.997 g/mL. However, we don’t use water to define the metric system anymore, so even at 4 °C - or more precisely 3.983035(670) °C - water is not exactly 1 g/mL.
1 mL. Studying chemistry has made that extremely useful and now other units seem ridiculous.
If we’re talking about geology or oceanography though, cubic meters are fine.
I like how 1ml of water weighs about 1g
1 mL of pure water weighs exactly 1 g at 20 °C and 1 atm pressure :) It’s a defined standard, useful for calibrating other things.

2000mL of water weighs 2kgs and 355mL weighs about 1/3kg.
To get my mind away from stupid imperial measures of weight, I think of bottles and cans of cola.
(Above is very approximate as sugar, packaging etc have weight. And conventional package size can vary by region.)
A liter of water’s a pint and three quarters
I prefer milligallons myself.
Wood Science must be a rather strange field.
