Example 1
- l = 2
- scale = 50000
100000
What is the length at 2 and scale 50000? 100000. Plain a×b.
Scale (length conversion)
Type the length on the map and the scale. L = a×b. 2 and 50000 give 100000. 3 and 1000 give 3000. 1.5 and 2000 give 3000.
Two fields, plain multiplication. The calculator does not know centimetres or kilometres. An integer product goes as a string, a fraction as six decimal places.

How it works
Map scale in this calculator is only a product. Length on the map times the scale. 2 and 50000 give 100000. 3 and 1000 give 3000. The engine calls a*b, nothing else.
The fields are l and scale. 1.5 and 2000 give 3000, again an integer string. 1.5 and 1.5 give 2.250000, because 2.25 is not an integer. The calculator does not append m or km.
An empty field is a blank value and a blank. Zero times the scale gives 0. A minus length gives a minus. The header units switch does not multiply anything.
This is not a miles-to-kilometres converter. This is not cylinder volume. Here two factors and a product.
1.5 and 2000 stay 3000 whatever the header label says.
2 and 50000 give 100000. 3 and 1000 give 3000. 1.5 and 2000 give 3000.
Formula
L = a × b
How to use
- Type the length on the map, for example 2, and the scale, for example 50000.
- Click Calculate. The real length comes out 100000.
- 3 and 1000 give 3000. 1.5 and 2000 give 3000.
- The calculator only multiplies. It does not add units.
- A product that is not an integer would get six decimal places.
2 and 50000 give 100000
Scale in this calculator is a×b. 2 and 50000 give 100000. 3 and 1000 give 3000. 1.5 and 2000 give 3000.
- scale
- The second field. 50000 with l = 2 gives 100000. 1000 with 3 gives 3000.
- length
- The first field l. 1.5 and 2000 give 3000. The calculator does not append km.
- conversion
- A product, not a map in the background. 2 and 50000 stay 100000.
Examples
Example 2
- l = 3

What is the length at 3 and scale 1000? 3000.
Example 3
- l = 1.5
- scale = 2000
3000
What is the length at 1.5 and scale 2000? 3000. An integer string.

Common questions
What is the length at 2 and 50000?
100000. 2×50000. The calculator only multiplies.
What does map scale mean here?
l times the scale. L = a×b. No units in the result.
What about 3 and 1000?
3000. A plain product.
What about 1.5 and 2000?
3000. An integer result goes as the string 3000.
Does the calculator add km?
No. The result is a number. The units label does not multiply.
What if a field is empty?
a blank value. The result stays blank.
Does 0 give 0?
Yes. Zero times the scale leaves 0.
When do you see six decimal places?
When the product is not an integer. 1.5×1.5 give 2.250000.
Does a comma in 1.5 work?
Yes. 1.5 and 1,5 are the same length.
Is this a miles converter?
No. Two factors, one product.
