How to use this calculator

  1. Enter the known values in the units shown. Results update as you type.
  2. Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
  3. Use the worked example to check the method. Reset restores the starting fields.

Use the result with context

Health results are educational estimates, not a diagnosis or treatment recommendation. A qualified clinician can interpret measurements in the context of your health.

Formula and method

Progesterone 10 ng/mL and estradiol 100 pg/mL give a mass ratio of 100 after matching units.

Ratio = progesterone concentration / estradiol concentration in the same mass units.

Worked example

Enter these known values and leave the other values blank.

Progesterone
10 ng/mL
Estradiol
100 pg/mL
Progesterone / estradiol mass ratio
100

Assumptions and limitations

  • Uses a mass-concentration ratio: 10 ng/mL divided by 100 pg/mL equals 100 after unit conversion. The number is not a hormone balance target or a diagnostic threshold.
  • Use the displayed units and measurements from the same context. Editable fields support arithmetic inverses when enough independent values are supplied. Clear a preset value before solving it as an unknown.
  • This tool performs the stated arithmetic model. It does not establish a diagnosis, prescribe treatment or replace laboratory and clinical assessment.

Common questions

What does this calculation represent?

Uses a mass-concentration ratio: 10 ng/mL divided by 100 pg/mL equals 100 after unit conversion. The number is not a hormone balance target or a diagnostic threshold.

Can I solve for a different field?

Clear the unknown field and enter enough independent values in the remaining editable controls. A relationship cannot recover a unique value when a dividing quantity is zero.
