Seal Strength Unit Converter
Rescale the reporting basis and convert newtons to gram-force. Normalization does not predict actual force at a different strip width or make test methods equivalent.

First time using this calculator?
Replace the example values with figures from your supplier sheet or measurements. Choose the unit beside each value. Results update as you type; fix any highlighted field before using the result.
GSM means grams per square metre. Net weight excludes the core and other packaging. MOQ means the minimum order quantity. An optional field can stay blank unless the result you need depends on it.
Prices keep the selected currency; changing its label does not convert an exchange rate. Save or export the result after checking your inputs.
Normalized force on target-width basis
Normalized N = Measured N × Target width/Test width; gf = N/0.00980665
force = 2; width = 15; target = 25; forceUnit = N → Normalized force on target-width basis = 3.333333333 N; Gram-force on target-width basis = 339.9054043 gfSaved calculations stay in this browser. No account or cloud backup is created.

The formula, made clear.
Rescale the reporting basis and convert newtons to gram-force. Normalization does not predict actual force at a different strip width or make test methods equivalent.
How to use this calculator
- 01
Confirm measured force, original test strip width, target reporting width, source force unit.
- 02
Enter consistent units; zero means a confirmed absence of a charge or allowance.
- 03
Review the arithmetic, rounding and limitations before using the result in a purchasing decision.
A calculation you can check
2 N per 15 mm reports 3.333 N or 339.91 gf per 25 mm.
- Measured force
- 2 N
- Original test strip width
- 15 mm
- Target reporting width
- 25 mm
force = 2; width = 15; target = 25; forceUnit = N → Normalized force on target-width basis = 3.333333333 N; Gram-force on target-width basis = 339.9054043 gfCheck the displayed formula and units against your quotation. Use measured GSM, net weight and actual layout dimensions where available. Default densities are planning assumptions, not certified material properties. Calculated cost does not certify strength, compatibility or safe loading.
