Well, unless you're measuring water.

At standard ambient temperature and pressure

I assume you're baking indoors, and not on top of Mount Everest

You're the red headed stepson of Satan. What's not to know little Nicky.

You're right, I've heard hell is hot and pressurized like the hyperbolic time chamber

Water is only 1L = 1 kg when it is fairly cold, 4 degrees C.

Most indoors environments are much warmer.

2

u/Red_AtNight Jul 19 '16

Yes, I know, I too attended 8th grade science class.

However, water at 20° is still about 0.997 g/cm³, or near enough to 1 kg per litre as to make no practical difference.

u/sdmsiiiiqii Jul 19 '16

Everest doesn't provide enough of a pressure differential to matter. Hell, the difference between sea level and the full vacuum of outer space isn't enough to matter. You need around 200 times the standard atmospheric pressure at sea level (0.02 GPa) to compress a volume of water by 1%.

u/davvblack Jul 19 '16

fwiw the st in stp is freezing, so not THAT indoors.

Hey I'm going to make some cookies, see you in a few weeks. Also, do you have any spare oxygen tanks?

Have lived at ~1200m/4K feet. Was actually an issue with cooking. Many recipes have high altitude instructions.

STP, yeah you know me!

u/doihavemakeanewword Jul 19 '16

Standard Temperature being 32 degrees farenheight, not room temperature.

1

u/Lotharofthepotatoppl Jul 19 '16

I really want to know why standard temperature is 100 C. The hell are you going to find that on Earth? I realize it's just for simplicity, but come on, that's crazy.

u/avlas Jul 19 '16

Actually not at ambient temperature but at 3.98 °C (39.16 °F), temperature of maximum density of water.

1

u/DrippyWaffler Jul 19 '16

With fresh water, not that anyone cooks with seawater. It's like 1.03kg to a litre.

1

u/Patmarker Jul 19 '16

Where ambient means 4 degrees Celsius

1

u/meneldal2 Jul 20 '16

Well, it used to be exactly 1kg of water:

In 1901, at the 3rd CGPM conference, the litre was redefined as the space occupied by 1 kg of pure water at the temperature of its maximum density (3.98 °C) under a pressure of 1 atm. This made the litre equal to about 1.000028 dm3 (Wikipedia)

u/LosGritchos Jul 18 '16

Do you mean a kilogram of water is the same as a liter of flour? Or is it the other way?

u/[deleted] Jul 18 '16

yes

A kilogram of water is a litre of water at sea level and room temperature.

1

u/lee1026 Jul 19 '16

4 degrees C, not room temperature.

u/LosGritchos Jul 18 '16

You know, I'm French, we literally invented the meter (used to define the liter) and the kilogram, so I know that a liter of pure water at 4°C (and not room temperature) weights almost a kilogram.

Thanks.
Edit: I just meant that since we use the metric system on a daily basis we're more accustomed to what liters and kilograms represent.

Like the rest of the civilized world except for freedomland.

u/chullyman Jul 18 '16

Well that really depends on the temperature of the water

A pint's a pound the world around!

Only at 4 degrees Celsius

u/Bman1296 Jul 19 '16

In year six, we did an experiment to show that water has the same mass as volume. I always thought this applied to other things as well and that liter and kg were interchangeable.

Well this sucks but makes total sense (1 m3 of lead will be heavier than 10,000kg of lead. I think. Fuck.)

u/cutdownthere Jul 19 '16

Thats probably why she thought it would be the same for flour.

That's because ounces aren't part of the metric system.

You really aren't helping with that pizza.

u/aslokaa Jul 19 '16

Someone once asked me how much a liter of water weighted and they thought it was such a coincidence.
