Converting metre to feet.
Converting units of a specific measurement from a single unit to another equivalent unit wasn’t easy. It had to undergo several internal conversions from one unit to another and then the actual value was found out. Maintaining the level of accuracy while conversion of units is very important as errors if occurred might affect bigger conversions. When conversions are done in the field of lengths and distances, there are a lot of units including the imperial and the US ones. That leaves us with a lot of minimal units that are still used over like Metre, feet, inches, yards too sometimes. What if we had to convert one form to the another, but we did not have the equivalence value? Like, what value we will get in terms of feet while converting metre to feet?
There are a lot of ways to do that.
We will mostly go through all of the simple ways, not any complex ones so that everything remains simple.
But first, let us understand the units a bit.
What actually is a metre?
Metre (not meter) is a highly common conventional unit used for measuring out small and long distances both along with other related units.
The metre is one of those units, which can be used on most of the measurements as a valid unit as it is highly convenient.
IT has mostly whole number values for either smaller units(up to picometre in terms of powers of 10) and even bigger units too (miles and Km).
The metre is extensively used in construction sites, road measurements, the field of view accuracies and lot.
What actually is a feet?
Feet is a smaller unit than the metre which is used widely around some countries. The fact that feet have high popularity and usage is due to its near convenient accuracy to the average length of our hand(only one half from palm circle to the elbow which is around a full complete foot).
The gap of the presence of smaller units between metre and centimetres is actually filed up feet. Not just feet, another smaller convenient unit known as inches is also used. It is smaller than feet but is bigger than centimetres(cm) and millimetres(mm).
It makes measurement easier when the lengths are too big for cm and mm. Feet are also used to measure out small lengths that are too big for cm, mm but small for the metre.
The need for an intermediate conversion unit.
The occurrence of an error is highly common when intermediate units are not used to convert one unit to another. Since conversion between bigger units directly on to themselves might give us the value we need.
But there might be chances of error when the value will be used to calculate bigger units and the error just keeps occurring more and more. Plus, we actually need equivalent values of the two main units (that we will be converting) in order to get our answer.
Without it, we won’t be able to do the conversion as we don’t have any other prior data to satisfy the convention. Choosing a unit, we can use centimetres in converting meter to feet.
So, when converting meter to feet, how much do we get the value? We will find out right now.
Let us first try out the old interesting physical method for converting metre to feet.
A simple distance level object conversion will do the best, as this is the simplest and easiest way to convert a unit to another.
In this technique, we will two scales of the different units to convert the one unit in the equivalent of the another by actually physically measuring one over the other.
To implement, first, we will require two long scales or sticks of some definite length. One should be of exactly 1 metre and the other should be exactly of one feet.
When converting the decimal values can be adjusted later to find out the exact number in the real form. So, at first, place the bigger 1-metre length stick on the ground at a steady level.
Then use the smaller 1 feet stick to measure itself on the metre stick and see how many times the stick goes to complete the whole length of the metre stick.
This will give you the idea of how conversions were actually done in the early periods. After doing so, you will find that the feet stick actually goes 3 times full, but still some length is left out.
So you can say that 1 metre is roughly equal to 3 feet and some length. To find out the extra length, we will do a simple error fixing on our feet stick. We will divide the stick into 10 equal divisions.
And you have to run the physical measuring out again. You will find that the feet stick goes around 3 times and 2 divisions along with another 80% of a full division.
The conversion value is now 3.2 from 3, which is accurate up to 2 divisions (40% accurate). To find out the 80% of the length in exact numbers rather than approximation, we will again do another error fixing.
The 10 divisions that you made, divide one of the division into again equal 10 divisions. Now you have smaller divisions equivalent up to two decimal places. Run the measurement again.
You will find that it goes for around 3 full feet, two bigger divisions, and eight small divisions. That gives the total of 3.280 feet for 1 metre.
And that is the answer actually.
Now that we know the actual answer, let us try with the modern intermediate conversion method.
Metres to centimetres.
Metres and centimetres go hand in hand with measurements and they are quite easy to handle when it comes to quick conversion.
A centimetre is a smaller unit and is equivalent to one-hundredth of a metre. Or reversely, 100 centimetre equals out 1 metre exactly. That simple and simple.
Feet to centimetres
We know the classic common answer to this conversion. And it is 30cm. Well, that’s just a rounded off answer which we never even cared about.
But now, we will use the actual value which is a bit more than 30cm. Even if you look at a perfectly calibrated feet scale, you will notice that the 30cm mark is already inside the 12inch mark, which proves that a feet is more than 30cm.
Apart and coming to the actual value, one feet equals out 30.48 cm to be exact. Do remember it and use it. This is the exact value and is around 1.6% more accurate.
The final conversion and our answer to our original question.
Now we come to our final conversion which will give us the answer. We already have tried out the physical measuring method with a metre and a feet stick (with prior error fixing divisions to get the fractional values too with high accuracy).
And that gave us a value of 3.28 feet for a metre. Now we will use math and unitary method for the conversion.
First, we have one feet equivalent to centimetres as 30.48 cm for one feet.
Secondly, we have one metre equivalent to centimetres as 100 cm for one metre.
Now converting meter to feet, we will have the divide the equivalent 100cm by 30.48cm which will give us a value of 3.280839 feet.
The measurement which we did with sticks physically thus proved to be actually correct and that too, up to 2 decimal places.
So converting meter to feet, we get 3.28 as the equivalent value.
