Compare Calculators

Health numbers — BMI, BMR, calorie needs, ideal weight — are the foundation of any fitness or weight plan. This Lean Body Mass Calculator computes one of them accurately so you can set goals based on your body's actual numbers rather than generic advice.

The calculation follows established medical formulas: the Mifflin-St Jeor equation for BMR, the standard BMI classification, and the activity multipliers used by dietitians to estimate total daily energy needs.

For Pakistanis, the same BMI and calorie standards apply, but body composition varies — which is why these tools are starting points, not diagnoses. Combine the number with professional advice for serious health goals.

Track the number over time rather than once. Whether it is BMI trending down or calorie needs changing with activity, the trend tells you whether your plan is working.

The currency converter is one of the most-used tools on GuruAlpha because exchange rates touch every Pakistani who sends remittances, pays tuition abroad, travels, imports goods or shops on international websites. It converts between the US Dollar, Pakistani Rupee, Euro, British Pound, Saudi Riyal and UAE Dirham using live interbank rates from our market feed.

The rates used here are interbank reference rates — the mid-market rate at which banks trade with each other. When you actually exchange money at a bank, exchange company or airport counter, you will be quoted a buy rate and a sell rate, and the spread between them is how the exchanger earns. So the converter gives you the fair value; the final rate you get depends on where you exchange.

For overseas Pakistanis, the relevant question is often the reverse: how many rupees will my dollars, pounds, riyals or dirhams buy? Because these currencies are among the most-remitted into Pakistan — from Saudi Arabia, the UAE, the UK and the US — the converter covers exactly the pairs that matter, showing both the unit rate and the converted amount in one glance.

Exchange rates move throughout the day in response to trade balances, interest rates, political news and central bank policy. The USD/PKR rate, in particular, has been shaped in recent years by the State Bank of Pakistan's management of foreign exchange reserves, IMF programmes and remittance flows. Because our feed refreshes regularly, the number you see here is a current snapshot rather than a stale reference.

Use the converter both ways — rupee to foreign currency for planning an international payment, and foreign currency to rupees for valuing remittances or overseas income. The unit-rate row (1 USD = x PKR) also tells you the direction of the currency: a rising number means the rupee is weakening against the dollar.
