I need to draw a line with a 1:50 scale ruler, I converted inches by multiplying them by 25.4 which gives me mm, I need to know how much do I round up or down for instance if I have 127mm do I stop the line at 100 or do I draw the line up to 125 in between the 100 and 150 tick since the increments go 50,100,150,200... 609 for example would I just round down to 600?
this is a weird question. typically we would use autocad or some other software, and just draw a line at 609 units.
if you're drawing with a pencil, try to draw as close to 1/10 or 9/100 past the 600 tick on the scale. as you said, 125 is half way between 100 and 150, so draw 127 to that point and if your pencil lead is fine enough, draw 2 past it. your margin of error is, at best, the width of your pencil lead. just get as close as you can.
keep in mind, 1:50 is a metric scale and is not the same as 1"=50'-0". for some reason i've seen a lot of architects write 1:50 as if it means the same thing as 1"-50'-0".
1:50 is a ratio. it means you're scaling 1 unit to 50 units. that could be inches (1"=50") or miles (1 mile=50 miles) or anything else, but it's a direct scale. that works better in metric, because their units scale in multiples of 10. inches, engineer scales, and architect scales don't really scale in multiples of 10 (though an engineer's scale is divided in multiples of 10).
'50' on an engineer scale means an inch is divided into 5 tick marks, which are further divided into tenths. 60 means an inch is divided into 6 parts, which are further divided into tenths.
a scale of 1"=50'-0" is a ratio of 1:600. in metric, 1:50 would actually be pretty close to 1/4" scale. if the OP is using an engineer scale rather than a metric scale, their drawing is going to be pretty messed up.
How do I draw a line with 1:50 scale ruler?

REALLY?
O.....an engineer's scale my mistake i thought you were talking about a architect's scale.

maybe this will help you sorry for the mishap with the scales.

This is ridiculous.
Go buy the scale already.
