About This Calculator
This calculator helps you convert weights between dumbbell and barbell bench press. It uses a standard conversion factor of 1.20, based on the common recommendation that barbell bench press typically allows about 20% more load than dumbbell press due to increased stability and control.
How It Works
- Select the conversion direction: Dumbbell to Barbell or Barbell to Dumbbell.
- Enter the weight you normally lift in that mode (either dumbbell or barbell).
- Click "Convert" to view estimated equivalent weights for the opposite movement.
- When converting from dumbbell to barbell, the result includes two estimates: one assuming you entered a single dumbbell weight, and one assuming a combined total weight.
- When converting from barbell to dumbbell, the result includes both total dumbbell weight and weight per arm.
Frequently Asked Questions
Why is the conversion factor 1.20?
Because most people can lift about 20% more weight with a barbell than with two dumbbells, due to better stability and balanced movement.
Can I use this calculator for other exercises?
This tool is specifically designed for bench press. For exercises like shoulder press or incline press, conversion may differ.
Do I need to specify if I entered one dumbbell or both?
No. The calculator automatically shows both conversion results when converting from dumbbell to barbell.
Is the result precise?
The result is an estimate based on common strength ratios. Your actual numbers may vary depending on experience, form, and muscle balance.
