Direct Answer
To count weight on a kg bar, add the plates on one side, double them, and add the bar weight.
Total kg = bar kg + 2 x plates on one side
20 kg per side
60 kg total
20 kg bar
20 + 10 per side
80 kg total
20 kg bar
20 + 20 per side
100 kg total
20 kg bar
Metric bar assumptions
Most kg gyms use 20 kg bars and 15 kg bars. If your bar is different, change the bar weight before trusting the result.
Good for shared racks
This is useful when someone leaves a bar loaded and you need the total before deciding your next warmup or working set.
Frequently asked questions
Does the bar count in the total?

What is 20 kg on each side?
On a 20 kg bar, one 20 kg plate on each side is 60 kg total.
