What's the Difference Between Grams and Milli-litres?

WARNING: These are some random deep thoughts for you to ponder about when you have time to spare. It's a great way to take your exhausted mind for a little 'mental vacation' though.

I've been vexed about this whilst doing my cake experiments: what's the difference between 100g and 100ml? After some deep thoughts, here's the answer that emerged in my mind:

Firstly, is 100g of water the same as 100ml of water? Essentially, yes. Then, why do we measure them differently?

Grams is the weight of a thing (because of gravity pull). For example, you weigh 50 kilograms. A 100ml bottle of water will weigh 100g if the bottle has no weight.

Milli-litres(ml) is the space or capacity or volume that a thing (only in liquid form) takes up say, in a container. Imagine a bottle with 100ml of water - there is no space in between the water molecules and what you measure is only water itself.

Therefore, you cannot measure solid things in ml, like flour - because there is air 'space' in between the dry flour even if it is very fine flour. If you measure 100g of flour and try to measure it in ml in a container, it'll be about 150'ml' because of the extra air space or less dense-ness.

In short, for liquids, grams is almost the same as ml - the weight and the volume of water is the same. Whereas solid cannot be measured in ml.

You can approximately measure solids in grams in a container, like a cup or a jug with pre-measured indications. But bear in mind that a cup of flour is not the same weight (lesser) as a cup of sugar because of the different density, closeness, dense'ness', or air space of the solid's molecules. So you need 'more' flour to have the same weight (100g) as sugar. See illustration below.

Okay, back to reality. Do come back for another round of mental vacation.

Honda Civic SIR: The VTEC Growl

When I was young and restless I loved to speed while driving. And I am truly thankful to be still alive and that no one was hurt. But I'll never forget that feeling... as an extract from a car magazine (WHEELS) skillfully explained:

... Once the turbine wheel starts boosting up at 3,000rpm, cold air is immediately sucked into the open turbine mouth...into the engine for a thorough combustion... with excess pressure getting relieved through a Blitz Blow Off valve audibly announcing sharp throttle lift-off.

This is where things start to really heat up. Once the tachometer exceeds 5,500 rpm, all hell breaks lose as the sound of the T28 turbocharger at its full 1.3 bar of boost is then drowned by the awesome VTEC growl as it hits its full 8,900rpm rev range at the third gear. By then, everything around would look seemingly dreamy, as your nose starts to bleed...

Ok, my nose did not bleed. But I wouldn't dare to speed now, esp. since I've had my child. I even feel that it starts to get dangerous when I drive above 70km/h (43mph). Once my friend even revved up to 280km/h on his Honda Blackbird, with me as the pillion rider. It was surreal. With only my fingertips left hanging on to my friend's waist, I almost flew off with my helmet! If someone were to do this to me now, I might faint. I guess, my heart can't take such thrills anymore.

Anyway, I've listed the rest of the vehicles we've owned before - just to savour those memories. Right now, as our family pocket is shallower, Jeff is even considering selling his car and taking the public transport instead. I kind of support him for that. Doesn't it feel lighter to own less?
 
Enjoy our rides!

He sold his '1st wife' to get me through university.


His Toyota Corolla 1.6.

Then, we traded this Toyota car with SIR. We almost fell off a cliff with it a few years ago! Phew..

Took this photo with my phone camera (VGA, hence the poor resolution) and sent to Tigger (hubby) who was in London for a one-month course. I missed him so much then that I voluntarily washed and polished his car. But that was the first and last time I washed his car.
 
Feelings of longing for him turned to horror and panic when I couldn't get him and when he did not return my calls after I saw the news and footages of London bombing (2005) being broadcasted. Thankfully, he was safe.
 
Seeing this picture brings me back to that horrifying but grateful day. But still, that was the last time I'm washing his car.
 
 
My Piaggio FLY 150 Scooter

Sold this scooter when I'm 2 months pregnant. Luckily, zero accident or baby Tigger won't arrive on earth.



My Suzuki Swift 1.5

After bidding farewell to my scooter I bought this car. Again, proudly zero accident - probably because I'm moving like a snail while pregnant. And I sold this car soon after I left my job. How is it going, darling?
 

His Mitsubishi Lancer Ex 2.0 MIVEC

The only vehicle we have now. And of course, my rusty but trusty old friend, Bicycle.
