Internationally accepted standard measurement is in meters, millimeters etc hence most drawings from present day architects are in millimeters. However many are used to measuring in feet and inches, therefore is important for you to convert a measurement done in S.I unit to feet and inches for a proper mental visualization of the space measurement.

Remember your primary school conversion

10 millimeter=1 centimeter

10 centimeter=1 decimeter

100 centimeter=1 meter

1000 millimeters=1 meter

1000 meters=1 kilometer

At spot approximately, one inch is taken as 25mm, hence to convert inches it will go in this format

1”=(25 x 1)=25mm

2”=(25 x 2)=50mm

3”=(25 x 3)=75mm

4”=(25 x 4)=100mm e.t.c

So for a 6” block or thickness of concrete we are only saying (6” x 25)=150mm

Converting this to meters, remember 1000millimeter (mm) is 1 meter(m), therefore divide 150mm by 1000mm=0.15m. The same formula applies to others.

For feet we use approximately 3.3 feet to 1 meter, hence we usually goes in this order

1 meter=3.3 feet

2 meter=(2 x 3.3)=6.6 feet

3 meter=(3 x 3.3)=9.9 feet

4 meter=(4 x 3.3)=13.2 feet

5 meter=(5 x 3.3)=16.5 feet

6 meter=(6x 3.3)=19.8 feet etc

These are close approximates to help in easily converting measurements from your drawing since most are familiar with inches and feet.

For areas of land you are to buy in Lagos is commonly 18 meters by 36meters or 60 feet by 120 feet though it may varies in some areas and for most of other states is 15 meters by 30 meters i.e 50 feet by 100 feet. So the area of a plot in Lagos is approximately 648m^{2} i.e (18m x 36m) and for most of other states is 450m^{2} i.e (15m x 30m)

Now to calculate areas of land,

An acre of land is approximately 4,047m^{2}

An hectare is 100m by 100m piece of land which is equals to 10,000m^{2}

An hectare of land is about 2.47 acres

An acre is approximately 0.405 hectare

Remember one plot is 648 m^{2}

therefore to know how many plots in an acre is

4,047 m^{2}/648 m^{2}=6.245 plots. Approx 6 plots

However for the numbers of plots in an acre for a plot of 450 m^{2}

is 4,047 m^{2}/450 m^{2}=8.9933 plots. Approx 9 plots

For the numbers of plots in an hectare therefore is

10,000 m^{2}/648 m^{2}=15.432 plots Approx 15 plots

Or simply put 6 x 2.47 acres =14.82 Approx 15 plots

And for a 450m^{2 }plot

10,000m^{2}/450m^{2} =22.22 plots. Approx 22 plots

Or simply put 9 x 2.47 acres=22.23 plots. Approx 22 plots

I can simply say txs to U.Dont listing to detractors

Fantastic. Very helpful. Thank you

Thanks

indeed educative n very comphrehensive

Great work, man. keep it up.

Your writings have been very helpful, you may not know it.

May our good LORD bless you.

Thanks.

Thank you very much.

Thanks a lot, more grease to ur elbow.

Thanks for sharing. Your site/blogs has been very helpful to me and my friends.

What percentage of a plot is 1sq.m because most of the tiles,pvc etc are sold per sq.m

This is educative and value-added to profitable knowledge. Thanks.

Sir,i’m very gratefull for ur help may good Lord continue to bless u and give u long life to do more Amen.

I got what i have been looking for over the years tru u. Thanks.

Thanks for the reply….u can contact me for your building plans and design for any plot of land via mail on tkatibi@yahoo.com ,just reach me there n we design and build ur dream house

Thanks for your analysis. But there is no standard measurement of a plot of land. A hectare of land or more can be a plot of land in an industrial areas, even in Ikeja GRA and Ikoyi most of the plots are sitting on 3000ms2. And the are all called a plot of land

Your write up is. very helpful… keep on

your good work..tnx

i have a question pls i have seen how to convert from( meter to) feet now my question is if i want to convert from (feet to meter) what do i do thank you

Great work dear, keep it up.
