0.16 m2 = 160,000 mm2
cm2 = (10mm)2= 100 mm2.
It's not "maths". It's spelled "math". The mathematics is spelled with an "s" because it counts for all of the numbers used in a mathematical expression, and not just one mathematic note. When using British English the correct abbreviation is maths not math.
6370mm2
That depends upon the maximum amperage expected through the cable (which generally depends upon the usage): Lighting circuits use 1.0 mm2 or 1.5 mm2 Ring mains use 2.5 mm2 Cookers and showers use 6.0 mm2 If you are unsure, get a qualified electrician to install the cable you need (recommended).
mm2
maths
maths
Quite possibly it is an abbreviation for "answer".
'Math' is the abbreviation for mathematics, or "Maths" in Australia.
mm2
They can be used for 'therefore' but I think that is only maths
Junior Certificate Foundation is my understanding of the abbreviation. Maths, English and Irish compulsory. Irish can be avoided under certain circumstances.
0.16 m2 = 160,000 mm2
1 cm = 10 mm so 1 cm2 = 10*10 mm2 So 80.2 cm2 = 80.2 * 100 mm2 = 8020 mm2
No it does not round to
cm2 = (10mm)2= 100 mm2.
